Hello,
I started a thread about this on a.cc :
https://www.allegro.cc/forums/thread/616526
Basically, when you compile an allegro program with the latest MinGW runtime
(3.21.1 or 3.22.2) and use -std=c++11, you get errors saying off_t is undefined.
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?
