• detecting a lot more compilers (stolen from CMake, admittedly, as they
were the first coming up at G**gle with usable #ifdefs)
• handling MIPSpro
• more system info on IRIX
‣ I/O redirection seems broken:
$ (date; date >/dev/null; date) | wc -l
1 (expected: 2)
‣ other than that: working fine
‣ -YBSD (default) and -YSYSTEM_FIVE don’t work, just -YPOSIX, somehow
• Fix $(…) to `…` for OSF/1 V2.0 /bin/sh
‣ this compiler is FUBAR though:
$ cat >t.c
main() { return (foo()); }
$ cc t.c
ld:
Unresolved :
foo
$ echo $?
0
$ ls -l a.out
-rwxr-xr-x 1 mirbsd users 10835 Jul 21 17:12 a.out
‣ it seems to have ucode, but man is not installed
• new mirtoconf check: mkstemp(3)
• if !HAVE_MKSTEMP (Ultrix), use tempnam(3)
• only use printf(1) if it exists (it doesn’t on Ultrix)
• a few more signals
• add S_ISLNK if the OS doesn’t define it
• add strcasecmp(3) proto for Ultrix (it _is_ in <portability.h>, but
only for -YBSD I think)
• fgrep(1) on Ultrix doesn’t do “-e ① -e ②”
10x DEChengst:#UnixNL for giving access
it can’t do -Werror, that’s why it mis-detects attribute support.
ignore the warnings (unused variables, uninitialised values, control flow)
as I checked them and they are not valid. gcc 1.42 (BSDi modified) compiles
a very fine mksh
| OSF1 rubbereendje.dechengst.nl V5.1 2650 alpha
with the vendor compiler:
| Compaq C V6.5-011 on HP Tru64 UNIX V5.1B (Rev. 2650)
| Compiler Driver V6.5-003 (sys) cc Driver
• the platform’s sig_t is incompatible too (simplify check)
• no compile warnings at all
• results in:
$ size mksh
| text data bss dec hex
| 327680 16384 17808 361872 58590
$ file mksh
| mksh: COFF format alpha dynamically linked, demand paged executable or object module not stripped - version 3.13-14
$ ldd mksh

• minor testsuite issues:
FAIL ./check.t:regression-13
unexpected stderr - got too much output
wanted nothing
got:
Successful
cat: output error
⇒ probably harmless
• works like a charm!
• DEC C on OSF/1 (10x Jupp the IceWM coffee pot maintainer)
• other stuff which doesn’t nuke a.out on failure
XXX this must be tested on *ALL* supported platforms!
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
