    Right so. Other thing is that gcc (or, more specifically, ld) by
default produces COFF symbols in executable, unless you specify -s.
COFF symbols are nice thing for everyone who will have your program
crashed. Then one may remember crash address, lookup in debugger
which function lives by that address and send you sane bugreport ;-)
COFF symbols have acceptable size, rarely doubling file size.
