gdb: no longer define __STDC_CONSTANT_MACROS/__STDC_LIMIT_MACROS
My gnulib fix at:
https://lists.gnu.org/archive/html/bug-gnulib/2015-11/msg00010.html
was merged upstream meanwhile and our gnulib copy now includes it.
As a concidence, Kevin was telling me today that these macros are
causing a build problem on FreeBSD:
common/common-defs.h:47:0: error: "__STDC_CONSTANT_MACROS" redefined [-Werror]
#define __STDC_CONSTANT_MACROS 1
/usr/include/sys/cdefs.h:408:0: note: this is the location of the previous definition
#define __STDC_CONSTANT_MACROS
(and a similar error for __STDC_LIMIT_MACROS)
The problem seems to be that we should be defining these input macros
before including any system header, but, we're not.
So let's just revert e063da67902e ([C++] Define __STDC_CONSTANT_MACROS
/ __STDC_LIMIT_MACROS for stdint.h). If this causes a problem
somewhere, we can re-define the macros higher up in the file, before
system headers are included.
