only for -YBSD I think)

i.e. uint32_t and uint64_t
• faking <stdint.h>: u_int32_t is not part of ISO C99, so
do not add it there
• add a test if u_int32_t is declared, for the sake of the
fucked up OpenBSD standard arc4random(3) declaration, and
define it to uint32_t if the former type is not available,
e.g. on Solaris or if we fake <stdint.h>
• fix detection of arc4random_pushb(3) and the prototypes
if one of the things above applied to our system
• fix detection of arc4random function suite prototypes if
they are added via an arc4random.c file in the srcdir, and
copy that file into builddir (if it does not already exist)
to keep these isolated from each other
based on a real-life bug report by cnuke@ at the Croatian restaurant ☺☻
unbreaks “set ±o arc4random” on Solaris, both SUNpro and GCC
• use DOWARN semantically correct
• support the Microsoft® C Compiler
• on Interix, disable msc's security checks, as it relies on
library functions not provided by Interix' libc (XXX mirtoconf this)

this one is muuuuch too verbose IMHO, _and_ it #defines __GNUC__ (eek)
any more either, and can make use of code sharing between detection
of sys_siglist and sys_signame (and the underscored variants); nuke
the now-useless signames.c file too (merge struct into histrap.c)
SIGABRT to SIGIOT (good), SIGCHLD to SIGCLD (necessary and reason),
SIGIO to SIGPOLL (the former also exists on mirbsd so okay); changes
on other OSes should be monitored by porters
car only slower, yes this is possible, and the resulting binary passes the
testsuite just fine), the definition of __RCSID() in <sys/cdefs.h> expands
to something with __attribute__((used)), which triggers a warning, because
__attribute__ in general is supported but the used attribute isn't. Thusly
always use our own strings and get rid of the MULTI_RCSID test (introduced
because __RCSID() on Darwin is inferiour).
Maybe we should fix <sys/cdefs.h> too? #ifdef __SUNPRO_C helps here.
it was #if solaris'd in R28, and the system I have access
on does declare it now (still Solaris 8)
this can be put back if anyone complains, of course.

thanks to Pascal “loki” Bleser (yaloki), darix, Martin Zobel-Helas, Steve
Langasek (vorlon) for tracking this bug down in two different instances
XXX u_int32_t is not ISO C99, but seems to work well enough
XXX if it fails anywhere, we'll see in the build logs
XXX apple doesn't have the standard uint32_t and API doesn't specify it
• sys_siglist_defn: rename to sys_siglist_decl as we're really checking
for the declaration in the headers; change wording to “check if … does
not need to be declared” since we don't need to declare if we don't use
• scan for arc4random, arc4random_push, confstr declarations too
• sh.h: confstr declaration is no longer #ifdef __sun__; sort
• mention Darwin failure in R29c, fix in -current
• also clean up core dump file
• on HP-UX 11i v2, <stdint.h> requires <stdarg.h> because it pulls in
a <wchar.h> generated from gcc's fixincludes… dunno, but it works…
• HP-UX 11i v2 on ia64 only works with -mlp64; the default seems to be
-milp32 which generates SIGBUS due to misalignment (due to optimisation?)
-> in theory, HP-UX works on both PA-RISC and IA64 in R29c
-> R29c doesn't contain support for AIX or Mac OSX though…

• enhance and stylify comments
• a little KNF and simplifications
• #ifdef DEBUG: replace strchr and strstr with ucstrchr and ucstrstr
that take and return a non-const char *, and fix the violations
• new cstrchr, cstrstr (take and give const char *)
• new vstrchr, vstrstr (take const or not, give boolean value)
• new afreechk(x) = afreechv(x,x) = if (x1) afree(x2, ATEMP)
• new ksh_isdash(str) = (str != NULL) && !strcmp(str, "-")
• replace the only use of strrchr with inlined code to shrink
• minor man page fixes
• Minix 3 signames are autogenerated with gcc
• rename strlfun.c to strlcpy.c since we don't do strlcat(3) anyway,
only strlcpy(3), and shorten it
• dot.mkshrc: move MKSH=… down to the export line
to not disturb the PS1 visual impression ☺
• dot.mkshrc: Lstripcom(): optimise
• bump version

precedence over POSIX/SUSv3 stuff and requires libbsd-compat which is

Note: during the entire compile, there are warnings like
| gcc: unrecognized option `-std=gnu99'
but these won't trigger -Werror since they are in the driver,
not in the front-end, so they are harmless, I guess. (I don't
know of a way to make them vanish, either.)
* "$e" and "echo" fixes for if the stuff begins with a -, and
quoting cleanup (where feasible, feel free to send diffs)
* cosmetics
I hereby name this baby "Mirtoconf".

* copyright: mention CVS changelogs as place of contributors' name
and credit information, too
* check.t, sh.h: bump
until now, set it to '@'
* if LDSTATIC is '@' make it '-static' if MKSH_SMALL, '' otherwise
Yep, this might break, e.g. Darwin or Cygwin. But let's test that.
where we had 'noreturn' etc. but no '__noreturn__')
* Scan for __attribute__((bounded)) and __attribute__((used))
if we have __attribute__((noreturn))
* To be able to scan if certain attributes give warnings,
scan for -Werror with a simple programme which hopefully triggers none
* Convert __attribute__((unused)) to __unused, noreturn -> __dead
* Unify other attributes
* Clean up typography a little more
* 'sigseen' in Build.sh goes away
* Signal name existence is checked in this order:
have our own¹ -> sys_signame[] -> _sys_signame[] -> build our own²
* Signal description existence is checked in this order:
sys_siglist[] -> _sys_siglist[] -> strsignal() -> NULL³
¹ Predefined list of items, for operating systems where we
cannot build² them, i.e. Plan 9 and Minix 3 (e.g. no $CPP -dD)
² The usual cpp(1) stuff
³ Changed later, see below
* Make $CPP test dependent on $NEED_MKSH_SIGNAME (others can
be added here, this is not absolute)
* Make signal name list generation² dependent on $NEED_MKSH_SIGNAME
* Fix check if the generation worked
* Guarantee that sigtraps[*].name and sigtraps[*].mess are valid
C strings; this makes the code shorter *and* removes a few pos-
sible nil pointer dereferences
* Embed autoconf'd usages of sys_sig* / strsignal / mksh_sigpairs
into inittraps()
* Check for each signal 0<=i<=NSIG that
name is not NULL or "" -> replace with ("%d", i)
mess is not NULL or "" -> replace with ("Signal %d", i)
name does not start (case-insensitive) with "SIG" -> name += 3
* In gettrap(), fix check if signal name starts, case-sensitive
or case-insensitive, depending on need, with "SIG" (bug from millert@)
Other changes:
* Build.sh: ac_test[n]() are documented
* Build.sh: ac_test[n]() can have negative prereqs as well now
* Build.sh: use <<-'EOF' consistently
* bump patchlevel to today
* improve output readability
I wonder if I should use ANSI escapes to make the results
from the configuration bold… but then, this'd look worse
in e.g. mc or less. Suggestions?
@Benny: this is why I don't use GNU autoconf: writing configure.in
files is, supposedly, easy - but nobody teaches you which
changes you have to apply to your source files. Here I know.
XXX one of these uses a gcc extension, ok for now tho
* don't include <ctype.h> any more at all

no longer either but the mksh just built, in the shebang line.
* mksh.1: rework prompt ($PS1) section, simplify example,
point to packaged dot.mkshrc example
* mksh.1: fix description of 'redraw' regarding redrawal
of prompts longer than one screen line
* all: bump version/date
(yeah, that's what you get from developing with a
16-bit MS-DOS(R) executable of your favourite text editor)
* lex.c, mksh.1: do not print the delimiting character for
not-to-be-counted character sequences (i.e. ANSI escapes)
in prompts any more, mostly because ASCII 01h is printable
on both Interix and Cygwin and I'm lazy
(this also fixes prompt width counting if a printable character
such as 'x' is used as delimiting character)
* lex.c: through printing the prompt character by character,
also print the delimited sequences if skipping, fixes some
prompt redrawal not honouring colours stuff while not totally
redrawing the entire prompt
* sync dot.mkshrc sample with FreeWRT r383
* add some stuff from src/etc/profile and contrib/samples/etc_profile
* sync the latter two with reality and shorten
