The !defined(__CYGWIN__) is not necessary because gcc for Cygwin doesn't define _WIN32. > /* Make sure open() function will be used with a binary mode. */ > /* on cygwin, we need something similar, but instead link against */ > /* a special startup object, binmode.o */ > _set_fmode(_O_BINARY); > #endif > > I'm using binmode.o at present, but I'd prefer to just make a func call > at the same place the WIN32-specific code does.

Cygwin has no such function call except for the per-descriptor function setmode (fd, mode). IMHO using binmode.o is much more elegant. The only other choice you have is this: extern int _fmode; _fmode = O_BINARY; _fmode is defined in crt0.o so you can simply access it if you like. But anyway, using binmode.o is much more elegant, IMHO. I don't see what speaks against using it.
