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?
