Re: [AD] Allegro + latest MinGW = off_t undefined

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

I started a thread about this on :

Basically, when you compile an allegro program with the latest MinGW
(3.21.1 or 3.22.2) and use -std=c++11, you get errors saying off_t is

mingw/include/sys/types.h defines off_t, but only in certain cases,
such as when _POSIX_C_SOURCE is defined before including it
(in mingwrt 3.22.2) or when _NO_OLDNAMES is undefined (in mingwrt 3.21.1).

So allegro programs compiled with -std=c++11 fail to compile.

What should we do?
