Hi,

Are you sure? I thought I read somewhere that it's two-pass for COFF
and three-pass for ELF. But I dunno, it's way beyond my
understanding!   :-/    I submit to your vast experience here.   ;-)

P.S. GNU ld still links all *.o into the .EXE even if not used. I find
that annoying. I was wondering why removing a #define and recompiling
didn't shave any output size until I proved that. I also know that
libs are better at being selective, so I ended up doing "ar rvs
libdoy.a *.o" and thus "-L. -ldoy" saved me a tiny bit (only 4k in
this example, but still ... !). Is this an inherent C problem or just
GNU ld? (Some Pascal compilers have "smartlinking", but perhaps it's
more complicated than I know.)
