GCC headers and DJGPP port

If you can guarantee that gcc won't change it's mind *again* I suppose
we could agree on something like this.  Historically, though, I've had
to tweak headers with each gcc release whether I "played by the rules"
or did my own thing.  For a long time, it seemed that gcc was going to
be a moving target no matter what I tried, so I went with the simplest
solution for me.

Unfortunately, DJGPP is a *dos* program, not a Win32 program.  That
makes things even harder (but not impossible).  We have popen()
and system(), but not fork().
