interesting - my x86_64 (pgf90 6.1-6) generates just 1.2 MB,
of which 77KB is text (according to 'file').

I think it's true that 2GB is large for text, but it's also not 
terribly relevant.  I don't see much problem caused by 64 instruction
addresses, since things like libraries seem to get along with 
32b fixups (mcmodel=small).  I have no idea what windows does.
