On FreeBSD like any other OS your program will be linked dynamically
with all needed libraries (libg++.a ?). So the additional 310KB are
somewhere in your system and loaded and linked at program startup but
they're not in the executable itself. On cygwin32 there is no such
dynamic loader/linker for UN*X-like libraries. So all needed libraries
get linked statically with every executable which of course makes them
One approach in reducing that size would be to write DLLs as
replacements for the UN*X-like lib*.a libs. But AFAIK that needs some
