[PATCH:libICE] Fix stdio.h include for asprintf.

[Cyril Brulebois]

asprintf is a GNU extension and one needs to define _GNU_SOURCE before
including stdio.h. Otherwise, the build breaks this way with
CFLAGS="-Wall -Werror":
|   CC     process.lo
| cc1: warnings being treated as errors
| process.c: In function ‘ProcessError’:
| process.c:672: error: implicit declaration of function ‘asprintf’
| process.c:672: error: nested extern declaration of ‘asprintf’
| make[2]: *** [process.lo] Error 1
