Something that seems odd: Documentation/Changes says to use gcc-2.91.66 but this old version isn't available as a Debian package!
Quote: Kernel compilation ================== GCC --- The gcc version requirements may vary depending on the type of CPU in your computer. The next paragraph applies to users of x86 CPUs, but not necessarily to users of other CPUs. Users of other CPUs should obtain information about their gcc version requirements from another source. The recommended compiler for the kernel is egcs 1.1.2 (gcc 2.91.66), and it should be used when you need absolute stability. You may use gcc 2.95.x instead if you wish, although it may cause problems. Later versions of gcc 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 be compiled with it. 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 or derivatives, be sure not to use -fstrict-aliasing (which, depending on your version of gcc 2.95.x, may necessitate using -fno-strict-aliasing). ...RickM...
