I got it working without crashing, but I still don't know if it is completly
right that way. Lem'me explain, to straigthen the thing out I want to do.
This thing should do the following :

Check for a match with _dos_firstfind() and if this match is found and loop
with _dos_findnext() until no more matches are found. I wrote it this way,
since I bet _dos_findnext() will be excuted after the loop, and if it finds
a match will recall the loop, until no more file matches are found. It
should work this way.

I use _dos-syntaxes simply because I want compatibility in DOS as well. I
might be working on another machine some of the stuff, and then I'd be
pretty messed up since that machine can't even handle WIN95, unless I am
badly informed and findfirst() doesn't care if it is WIN or not.

Btw : Do you know how to clear the keyboard buffer after calling bioskey(1)?
