That comparison is not very meaningful unless you made sure both
compilers in question are the same GCC version, and generate the same
type of debug information.  DWARF2 debug info is quite a bit more
voluminous than DJGPP's usual format (stabs).

Try 'size -A' on both executables to see where all the size goes.

Use bsdsymify instead, and it should work.  Default 'symify' doesn't
understand either -gstabs or -gdwarf2.  That would man the
DJGPP-native compiler you're using so far is old enough to still have
'-gcoff' as its default debug information format.
