+have not received much testing for Linux kernel compilation, and there are 
 almost certainly bugs (mainly, but not exclusively, in the kernel) that
 will need to be fixed in order to use these compilers. In any case, using
 pgcc instead of egcs or plain gcc is just asking for trouble.
 
 Note that gcc 2.7.2.3 is no longer a supported kernel compiler. The kernel
 no longer works around bugs in gcc 2.7.2.3 and, in fact, will refuse to

+The Red Hat gcc 2.96 compiler subtree can also be used to build this tree.
+You should ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build

 In addition, please pay attention to compiler optimization.  Anything
 greater than -O2 may not be wise.  Similarly, if you choose to use gcc-2.95.x
