Hello everybody, a strange problem with the cobalt port's libc
(speculation, see below). Consider the following programme:
#include <stdlib.h>
int main() { (void)alloca(14); return(0); }
This compiles and runs fine as:
$ uname -rm
3.0.1 cobalt
$ gcc foo.c
$ ./a.out
But when compiled as such:
$ gcc -std=c99 foo.c
/var/tmp//cc9lV8g8.o(.text+0x28): In function `main':
: undefined reference to `alloca'
This behaviour occurs on NetBSD 3.0.1 cobalt (I'm technically emulating
with gxemul but this behaviour has been reported natively, specifically at
http://archive.lists.bsd.lv/sysjail/msg00007.html).
This compiles without flaw under i386 3.0 - I don't have a 3.0.1 i386
handy to see if this is an error between versions (versus between ports).
$ uname -rm
3.0 i386
$ gcc -std=c99 foo.c
$ ./a.out
Thoughts? Thank you!
Kristaps
