First of all you need an EXE compressor like 'DJP.exe' (check the DJ
archives).
It also supports DJGPP "Dynamically Loaded Module" (DLM) technology.
If your program doesn't need parts of the startup code, it can be made
smaller by defining certain functions with empty bodies.  These functions
are
`__crt0_glob_function', `__crt0_load_environment_file', and
`__crt0_setup_arguments.' By defining empty substitutes for all three of
these, you can make the "Hello" program be 18KB on disk.  These functions
are
documented in the DJGPP libc reference, which see. 
Also see the section 'Reducing your executable size' in allegro.txt, and
then recompile your source code.
