It shouldn't have been specified static because the C standard requires that 'any declaration of a library function shall have external linkage' (N2176, 7.1.2, 6). The static specifier might exist for a reason, so please prepare a patch and send it to our mailing list for further discussion.

Hello, I have an issue with mingw-w64: My program, which uses Allegro 4 to show some graphics and prints a bunch of debug info to stdout, runs terribly slow when compiled with mingw-w64 (ye' olde mingw32-gcc is fine) and run inside a regular conhost window or using winpty. I'm talking two orders of (frame rate) magnitude: Regular conhost: 10 FPS game Regular conhost, redirect to NUL: 58 FPS game >NUL minTTY: 1200 FPS (goes down to 240 after a couple seconds due to more debug messages) mintty ./game...

Hey, just came here by a Google to missing "libgfortran-5.dll" and thanks to you I found it out. In my case, I am using MSYS2 on Win10 with installed mingw-w64-x86_64-toolchain. I finally found the DLL in "C:\msys64\mingw64\bin".
