Solaris 10 x64 Compiling issues with Sun Studio 12

Hello, I'm having problems compiling Ruby 1.8.5 on a 64-bit Intel machine running Solaris 10 U3.

I'm using Sun Studio 12 for building an optimized package for our company. We're not interested in coolstack (from Sun used with GCC). Any help below would be appreciated:

I've tried the various compiling options below (and various CFLAGS with no luck)
