According to <http://developers.sun.com/sunstudio/products/faqs/cpp.html#q1 > this preprocessor symbol is a 3 digit hex number.
On Studio 11 (SPARC) it is 0x580. On Studio 12 (SPARC) it is 0x590. On Studio 12 Express (x86) it is 0x5100 :-) Is there a new rule for calculating the major/minor release numbers? Cheers, Chris
