Package: libc6-dev
Version: 2.10.2-8
Severity: minor

The INTMAX_MAX definition in /usr/include/stdint.h yields build
failure in 32-bit C90 mode (x86_64 machines with the -m32 gcc
switch and x86 machines).

$ cat intmax-test.c
#include <stdint.h>
int main (void)
{
  intmax_t x;
  x = INTMAX_MAX;
  return 0;
}
$ gcc -m32 -ansi -pedantic-errors intmax-test.c
intmax-test.c:5:1: error: use of C99 long long integer constant

Support for intmax_t is not expected to work in C90 mode, but in
such a case, the failure should probably occur on the <stdint.h>
inclusion or "intmax_t x;" line. Otherwise I wonder whether the
failure on INTMAX_MAX is intended and/or fixable.

The consequence of this inconsistency is the following: for a
software that uses intmax_t optionally (such as MPFR), as intmax_t
works fine, autoconf detects that intmax_t is supported, but then
the build of the software fails if it uses INTMAX_MAX.

Closing this old bug since the issue was eventually fixed in GCC 4.8:

ypig% gcc-4.7 -m32 -ansi -pedantic-errors intmax-test.c
intmax-test.c: In function ‘main’:
intmax-test.c:5:1: error: use of C99 long long integer constant [-Wlong-long]
ypig% gcc-4.8 -m32 -ansi -pedantic-errors intmax-test.c
ypig%
