I've reassigned this bug to libc as the problem also exists there when
run with "gcc -I/usr/include -I/usr/include" and that the elf-*
packages will possibly be going away before this gets fixed.

Consider the following program:
-- demo.c --
#include <limits.h>

int main(void) {
  if (3 > SHRT_MAX) {
    exit(1);
  } 
}
-- end --

when this program is compiled for a.out (gcc-2.6.3-4, libc-4.6.27-5)
using "gcc test.c" or "gcc -I/usr/include test.c" all goes well;
when it is compiled for ELF (in an environment with /usr/elf before 
/usr/bin in the PATH and /usr/elf/gcc -> /usr/bin/gcc-elf etc)
it compiles fine using "gcc test.c", but 
"gcc -I/usr/i486-linuxelf/include test.c" results in:
--
test.c: In function `main':
test.c:4: `SHRT_MAX' undeclared (first use this function)
test.c:4: (Each undeclared identifier is reported only once
test.c:4: for each function it appears in.)
--

I'm not sure whether this is actually a bug or not, I just think it
is a strange difference between a.out or ELF.

/usr/include/limits.h differs from /usr/i486-linuxelf/limits.h only
in that it has some extra #ifdef'ed code for __SVR4__I386_ABI_L1__.
The posix1_lim.h and posix2_lim.h files are identical for a.out and ELF.
