OK, so I exaggerated ^_^  I'll check it out and do a complete walk
to be sure. Thanks for the tip on the locale function though. I
shouldn't need support for that in this particular piece of code.

Yeah, its easy to get code over CVS. I meant it would take a long
time if I wanted to fully upgrade my DJGPP installation.

I actively maintain this program. Besides adding tons of features and
bug fixes, I've also ported it to several other platforms (on which it
uses SDL rather than Allegro).  I only still support DOS because its
relatively easy to keep it working, and there's a few very oldschool
people in the DOOM community that prefer it. The code that is in
question here is a "portable" snprintf implementation which I have added
recently because some of my target platforms totally lack or have
questionable implementations of snprintf and vsnprintf. It uses the
fcvt function in one place in its double formatting code.
