Just keep in mind that the gnu compiler is not supported by Oracle. This doesn't mean that it won't work, but it does mean that Oracle hasn't tested it and makes no guarentees. If there is a problem that doesn't reproduce with the supported compiler on your platform (on Solaris it is the SparcWorks compiler) then you are on your own. Check the IGC for your platform and version to find the supported compiler (and the version of the supported compiler).

For example, on Solaris you can get an undefined symbol __cg92_used. If you are using the SparcWorks compiler, then you simply use the -xcg92 flag. But gcc has no such option. This is just one possible problem.
