You could also declare a global object thus:

class FModeFixer {
	FModeFixer(int m) { _fmode = m; }
};

FModeFixer _fmodefixer(O_BINARY);

which will of course get called before main if you just make
sure it gets linked in by putting it into some essential .o file.

This avoids changing the library.

I used this approach (at DJ's suggestion) to initialize the gppconio
library many moons ago.
