The ever helpful setting of -g into CXXFLAGS by AC_PROG_CXX is incorrect
on Sun Studio (IMHO). Currently, the test checks for Sun Studio compiler
and, if so, injects -g. The problem is, -g on Sun Studio means "include
symbols _AND_ disable inlining" The appropriate flag that's similar to
-g on GCC is -g0. (Thanks Sun Studio, for being weird)

I suspect that in this case GCC is being weird since GCC differs from other compilers. However, I agree that -g0 much better for the Sun compiler when used with optimization allowed/enabled (-xO3 is Sun compiler default), and it is what I use in my own optimized debug builds.
