The smallest I could get it, using -Os, -fno-exceptions, no optimization,
and -s was 950K, still 50% bigger than VC++.
I think it's the template code that might be big. It uses templates all
over the place, templates which don't compile using gcc. Can anyone
confirm this? I don't know if it's something that can be reduced to
a simple case. (I could be wrong, too. :)
It's also interesting that linking it with cc1plus as opposed to cc1
results in a binary 24K bigger, because, according to the linker, it
links in file io stuff from /usr/lib/stdc++. The final binary which
dynamically loads it presumably has those routines available, and is
compiled with -Wl,--export-dynamic, so it should pick them up.
Also, when linking with either cc1 or cc1plus, and specifying
-fno-exceptions, the exception.o object from libgcc.a is still
linked in.
Ideas?
