Unfortunately, UPX is not able to compress the FPC 3.x.y files for DOS/GO32V
2 because their COFF header is slightly different then header from DJGPP.
However, supprisingly, the 32Lite compressor works OK for them.

Since FreeDOS 1.4 is fast approaching, I think this should be put off until
after that release.
While UPX compressing the binaries “should” have no ill effects, they would
need still need tested. I don’t think there is sufficient time to do the
proper testing before 1.4 is released.
I think we should leave them as-is for now.
