In my case the user flags need to be last otherwise the addition of "-g 
-O" or even "-g -xO2" removes the heavier optimizations I've already set 
in CFLAGS. Why not have a default set of CFLAGS but if the user has 
already set one then the users flags are taken without additions or 
modifications?

The compiler outputs errors. It doesn't stop working but I get lots of 
output about how fsimple and the like aren't flags to pass to the compiler.

Solaris i386 using the Sun compilers and not gcc. I'm not sure what the 
gcc flags you've set do but I'd perform a check that says, "If we're not 
using gcc then don't set MATH_CFLAGS".
