Just looking at top and my watch.
Tested with -O2.
CPU is Celeron 466Mhz with 384MB RAM.
[yohgaki@dev HEAD]$ uname -a
Linux dev.localnet 2.4.18-10k #1 Tue Mar 12 21:42:04 JST 2002 i686 unknown
[yohgaki@dev HEAD]$ gcc -v
Reading specs from /usr/lib/gcc-lib/i586-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Kondara MNU/Linux 2.1)
Compiler used about 20MB and took about 30 seconds to compile it.
-O3 does not make much difference.
We need to test with GCC3 and other platforms, though.
