I have run into a quirk of GNULIB building CVS on a FreeBSD 4.2 host.
It seems that CVS is using m4/intmax.m4 which generate these lines
into the config.h file:
/* Define if you have the 'uintmax_t' type in <stdint.h> or <inttypes.h>. */
/* The size of a `intmax_t', as computed by sizeof. */
/* Define if intmax_t is the first integer type detected with its size. */
#define intmax_t long long
#define uintmax_t unsigned long long
However, the stdint_.h file has the lines
typedef int32_t intmax_t;
typedef uint32_t uintmax_t;
which can cause a problem...
Observation: On a FreeBSD 4.2-RELEASE host, I get the following warnings
when building the md5.c file on the CVS mainline sources...
The problem arises from these two lines
typedef int32_t intmax_t;
typedef uint32_t uintmax_t;
being expanded into these two lines:
typedef int32_t long long ;
typedef uint32_t unsigned long long ;
which is clearly not going to do the right thing.
I believe this should probably fixed in the GNULIB sources, but I do not
know what the best fix to suggest might be.
Thank you,
