Or maybe replace off_t with int64_t - the uses I can see seem very suspicious, and most likely currently Allegro 5 will break if it is ever compiled on a system where off_t is only 32 bit.

Sounds like the proper solution is to define _POSIX_C_SOURCE then, perhaps guarded by a check for ALLEGRO_GCC.

All of these errors have been fixed by patches issued by Keith Marshall of MinGW, as detailed here :


So as far as I can see, Allegro 5 programs now properly compile with the C++11 standard in use.

Do we really need to replace off_t with int64_t though? I mean better safe than sorry, but are we really ever going to deal with file system entries larger than 4GB? Where does the issue with using off_t on 64 bit systems come in? If we needed file system offsets I would agree that int64_t would be better, but I don't see any of that in use at the moment.
