I disagree.
First, it should be >= since 2.8.0 is the _buggy_ one. 2.8.1 is or of the
misfeatured one (or so).
Some apps require 2.8.1 already, and we shouldn't force anyone to have 2
compilers installed, one just for the occassional kernel compile ;)
(and not everyone has a girlfriend to warrant a 386 dedicated kernel compile
machine (DKCM) :)
So far, i know of one _big_ problem in arch/i386/kernel/ioport.c (which i
so far copied from 2.1.97), that could be fixed somewhat... like...
#if GCC_VERSION == 2.8.0
#error Your compiler is buggy, please up- or (better) downgrade
#endif
and in ioport.c some
#if GGC_VERSION > 2.8.0
to enable the work-around, maybe even a message in the bootup "non-compliant
compiler used, nothing guaranteed". And one should find and nail any other
incompatabilities ;)
