It looks to me like the configuration is defining the standard C types
'ptrdiff_t', 'size_t', and 'ssize_t' when it doesn't need to.
Was there a 'config.cache' file left over from a previous build or
build attempt when you ran 'configure'?

Do a 'make distclean' and try running 'configure' again.
If you still have the problem, send us the config.log and libsrc/ncconfig.h.

There is also a slight chance that your compiler is installed incorrectly,
but that would show up on other code as well. If this were the case,
the following standalone code probably would exhibit the problem:

==== snip & compile ====

#include <sys/types.h>
#include <stddef.h>

long
func(void)
{
        size_t p[10];
        ptrdiff_t d = &p[9] - &p[0];
        return (long) d;
}
