Funny, it does not
{{{
#!C
#define __STDC__ 1
}}}
which might be the cause and a bug in GCC 4.5.0, so you could try adding
`-D__STDC__` to `CFLAGS`.

Did you try any of the `-std=...`?
You could also try just
{{{
#!sh
gcc -std=gnu99 -E -dM -x c /dev/null | egrep -i "std|ansi|iso|posix|gnu"
}}}
and see if `__STDC__` gets defined then.

:) You're not familiar with the C/C++ preprocessor?
It just adds a meta-level (all directives on lines starting with `#`) and
has things like `define`, `undef`ine, `if` or
`ifdef`inded-`elif`-`else`-`endif` and the usual expressions in
`if`-conditions, and of course also `include`.
You usually have constructs like
{{{
#!C
#ifdef __IMPORTANT_MACRO_SIGNALING_A_STANDARD__
// define the constants and functions required by that standard
#elif defined(__OTHER_IMPORTANT_STANDARD__) || defined(__SOMETHING_ELSE__)
#include <file_that_accommodates_these.h>
// perhaps other C declarations and macro definitions
#else
// perhaps define things that oppose the standard(s)
#endif
}}}
in C header files like `unistd.h`, located in `/usr/include/` or
`/usr/local/include/`.
