I am using CygWin B20. I wasn't aware that there was something like a "Mingw
compiler", since the only reference to Mingw that I have seen is the header
files and the mingw32 library included with CygWin B20...

Where can I get this Mingw?

As I said, there are prototypes in mingw32/dir.h, but the program refuses to
link if I call the functions prototyped there. If I grep for _findfirst, I
find it in the libmingw32 file, but it won't link even with that one.

And for using Win32 calls, from what I figured from the FAQ, I need to write
-mwindows to do that, and that will turn the program into a GUI application,
which I do not want...?
