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.
to strcasestr, it was used in a wrong way (reverse logic error in
checking its return value), turning to mis-detection of UTF-8 locale.
* sh.h, check.t: bump version
* copyright: bump year

Compute user-given ulimit value times ulimit unit as an rlim_t value, not a
long value; catches some 32 bit overflows on 32 bit platforms.
Found by drahn@, ok otto@
"set +o emacs-usemeta" and "set -o vi-show8" which are always on now,
since we have proper internationalisation (i.e. utf-8) support, and
assume the user either has a 'C' locale and can't enter 8-bit chars,
his terminal is 8bit-transparent, or he has a 'UTF-8' locale.
twkm (from #ksh on freenode), that $RANDOM is always an unsigned
15-bit decimal integer.
(RANDOM << 15 | RANDOM) thusly yields 30 bit, which is still more
than 36^5, so we can use it on the baselife CD to speed things up
cought by crib in IRC, thanks
(our textproc/groff port is unaffected since it uses the MirOS implementation,
a BSD derived one with fixes, by default instead but can reproduce the defect
with -mgdoc instead of -mdoc as parametre)
main.c: In function 'main':
main.c:208: warning: cast discards qualifiers from pointer target type
main.c:329: warning: cast discards qualifiers from pointer target type
no warnings at autoconf time left either; will take care of these two later
(might revisit changes from this commit), maybe change declararion for the
builtins to have their argv[] be const strings, and go through strict type
and qualifier checking again. this'll further improve stability.
XXX these changes might have introduced (more?) memory leaks,
XXX someone who knows about these tools should verify with
XXX automatic memory usage analysers (valgrind?)
still passes testsuite
