Hello Aleks. I found that the "#if defined(int64_t)" is not working (the previous "#ifdef int64_t" didn't work either... my fault) in pdf-types.h. This means we have always been compiling our own 64-bit support.
Attached is a patch to check for int64_t at configure time, which seems to work ok. We are including gnulib's stdint.h in pdf-types.h. Is this change aware of that?
