I hope this is the good way to use GNUlib;
let me now if I made something wrong.
Index: ChangeLog
from BenoƮt Perrot <benoit(a)lrde.epita.fr>
* config/stdint.m4, config/inttypes.m4:
GNUlib's <stdint.h>/<inttypes.h> detection tools.
* configure.ac:
Use gl_HAVE_STDINT_H to check <stdint.h>/<inttypes.h> presence.
Define __STDC_LIMIT_MACROS to access to some macros that
the ISO C99 standard specifies to be explicitly requested
in C++ implementation.
* src/stdint_.h:
GNUlib's "ISO C 99 <stdint.h> for platforms that lack it."
* src/Makefile.am:
Generate stdint.h from stdint_.h on platforms that lack it.
* src/vm/cpu.hh, src/vm/memory.hh, src/inst/data_section.hh:
Include config.h to get information on <stdint.h>/<inttypes.h>
presence.
