Hey all,

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)

Revisiting an old thread.  Thanks for the report; any suggestions on how
to fix it before the release of autoconf 2.66?

Note that this weirdness only applies to the C++ compiler. I don't believe that the C compiler will accept it.
