Hi !
I'd suggest to add something to the CPP_PREDEFINES... Here the self
documenting patch ;-)
BTW: Could compile /usr/src/bin and /usr/src/sbin without any
trouble using -pipe -mpentium -O6.
Compilation with -6 only failed in /usr/src/usr.bin/tftp.
gcc got fatal signal 6. With -05, too. Optimization level -O4
worked ok for this subdir.
[ Kernel compilation failed, Jordan ;-) ]
Another thing... When bootstrapping gcc it will be build using
the CFLAGS -O2. Should we perhaps change this to:
-pipe -mpentium -O2 ???
