Hi,

Just committed this:
Removed -pentium Options for Solaris Intel Pentium
Changed -p4 Use optimizations specific for the Intel Pentium4 processor
to -sse Use optimizations for the SSE family of vector processors
This still needs work esp for gnu and intel where there are many options.

bbl,
scott
