Comment(by guest):
I managed to track down the problem. Turns out that the header in
question indirectly includes <sys/types.h> before it includes <stdint.h>,
and <sys/types.h> defines int64_t in a way that c2hs doesn't know how to
handle:
{{{
$ cpp /usr/include/stdint.h | grep -w int64_t
typedef long int int64_t;
$ cpp /usr/include/sys/types.h | grep -w int64_t
typedef int int64_t __attribute__ ((__mode__ (__DI__)));
}}}
I'd guess that c2hs ignores the GCC-specific __attribute__ that
overrides the size, and just sees "int".
