Like I said, chapter 8.15 of the FAQ describes ways to reduce the size
of DJGPP executable files without using any external code like DXE or
DLX (or DLM or whatever...). The steps to take are as follows:
- Include <crt0.h>, and define empty versions of one or more of these
functions: __crt0_glob_function(), __crt0_load_environment_file(), and
__crt0_setup_arguments(). Look them up to see the proper argument
syntax; for example, your __crt0_glob_function() should return NULL.
You can only do this if you don't need the services that those functions
provide: namely, command line globbing, loading environment settings
from 'djgpp.env', and creating main's argc and argv.
- Use the DJP executable packer, which can runtime-compress DJGPP
executables. It's available on SimTel as v2misc/mlp106b.zip.
Since the startup code comprises about 90% of that 50K executable,
breaking the library code out won't help in the slightest.
