Hi all.

Warning: these questions may appear slightly OT.

I have been experimenting in compiling my DJGPP-intended programs using gcc
in Linux.  Unfortunately I'm having lots of trouble (this is not alleviated
by the fact that I'm not Linux-adept).

1. I have a disquieting feeling that doing graphics stuff in Linux is
tricky.  For example when I try to run the examples that come with the
Allegro WIP, I get errors about Mode-X (this only happens for some of the
examples).  Does a program need to do stuff with permissions in order to
change video mode, or something?

2. Backslash-newlines, which i use occassionally for the more complicated
#defines, aren't recognised by cpp, apparently because of the CRLF problem.
Is there a simple way I can get around this?  I'd like to be able to compile
the same sources that I edit with RHIDE in dos.

3. Lots of functions I use often in DJGPP, usually in connection with files,
simply don't exist in the linux library.  (But I can get around this by
using more complicated things like fstat().)  Still, the question remains...

Thanks,
Edmund.
