An example of the error: In the include file is: +168 extern int link(const char *, const char *); +169 extern off_t lseek(int, off_t, int); +170 #ifdef _LARGE_FILE_API +171 extern off64_t lseek64(int, off64_t, int); +172 #endif Lines 169 and 171 look different enough.

I suspect that - MAYBE - this was important for when 32-bit hardware was out there (in 1997 64-bit file support was added to AIX 4.2.0 even though the kernel was still 32-bit as well as 'normal' pointers. In any case - this was not a problem I encounter with fontconfig-2.4.2 (ancient!!) but do now. Give me hints, and I shall test them (as I have time). Sincerely, Michael </div>
