[svn-r6439] Purpose:
Bug fix w/gcc 2.95.x where x<3
Description:
-O3 optimization level causes problems for gcc 2.95.2 on eirene
Solution:
Only enable -O3 if using gcc 2.95.x (where x>=3) or gcc 3
Otherwise, use older setting of -O2 -finline-functions
Platforms tested:
FreeBSD 4.7 (sleipnir)
Linux 2.2 (eirene)
