LibRaw depends heavily on Dave Coffin's dcraw utlility. I've copied -O4
option from dcraw page
(http://cybercom.net/~dcoffin/dcraw/)
Anyway, just tested it on FreeBSD7/i386 on Intel C2D
Execution time for LibRaw test is near same for -O3 and -O4
There is significant difference between -O2 and -O3 (about 10%)
So, you can change to -O3 in port Makefile patches
I will also change to -O3 in future LibRaw releases.
