AFAIK, no. You'll have to convert them into some other format manually. I
think there may be some code somewhere that will, but I don't know where.

Is this from RHIDE? If so, you need to add this line to
c:/djgpp/share/rhide/rhide.env:

RHIDE_TYPED_LIBS_DJGPP.cc=stdcxx

Create the file if it doesn't exist.

Sure, just blit the next one to some other position. See the Allegro docs on
`blit'.

Yes, that's a general C question. Try comp.lang.c for that.

IMHO, Allegro is the best at what it does. There's also GRX, which is solely
a graphics library, and lacks the game-related features of Allegro. As far
as I know, it is less optimized for speed and such, though it does provide
more graphics modes (especially for < 256 colors), and is portable to Unix/X
Windows and Linux/svgalib.
