A DJGPP EXE is a stub plus a COFF. The stub handles going
into protected mode and loading the COFF. It really is overkill
for a hello program:

should be int main(void) to comply with ANSI C

Half of a typical program is debugging symbols. Did you strip
them out with the strip command? It should drop to 40 kilobytes.
DJP (see the FAQ) should shrink it further.

DOSArena is slightly over a megabyte unstripped and
uncompressed. UPX, the Ultimate Packer for Executables,
strips and compresses your binaries in one step. It can also
make your Windows 9x programs a lot smaller.
