Yes.  A compiler and library on one system produces an identical
binary to that produced by the same compiler and library on another
system.

You need the .exe file and any Allegro datafiles you're loading with
load_datafile().

These are statically linked in DJGPP; all the libraries are part of
the EXE file.  However, you might want to use Allegro's binary size
reducing options if you're distributing the binaries across a network:
  info allegro reducing
The UPX executable packer (http://upx.tsx.org/) wouldn't hurt either.
UPX can reduce the Allegro overhead to 200 KB with all features
enabled.
