Try using executable packers:
with DOS port I now have 513K size, while it was about 2M before.
and a higher optimization level: on DOS, -O3 gives 1.1M
but no optimization leads to 2.1M executable (no significant
difference if using packers, though).

No, not in makefile. You can just not include few chartrans tables
in UCDomap.c, read chrtrans/readme.tab
The effect not so impressive: UCDomap.o hold all tables
and have a size of 260K but only 78K if packed.
You can safely exclude long "mnemonics" tables,
and probably all DOS cpXXX tables if you don't expect users with
such display charset (but leave windows-XXXX, lots of such pages around).
This may gain about 150K or 30K compressed.
Other chartrans code heavily build-in.
Exclude old-style options menu.
