Recommended GCC version?

[David Holmes - Sun Microsystems]

Do we need to be careful about the word "recommended" here? There is a 
big difference between "compiles fine" and "works fine". Anyone using 
alternate compilers to build the JDK (Hotspot in particular) may 
encounter compiler specific bugs at runtime.

Do we have a big disclaimer/warning somewhere about this? Any bug 
reports would need to include which compiler was used.
