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)

config.log shows the following
