(sorry if this is my second post, my email is a bit funny today)

i am trying to bootstrap the gcc-3.0 under linux mandrake 8.0, it threw
back this error when it started (see end of message) compiling the final
gcc-3.0 after all the bootstraping..... so i figured maybe this is a
problem with mandrake using 2.96, so i downgraded to 2.95.3 (that went
smoothly by the way)
but still the exact same error occurs at the same place when i cleaned
the tree and started again. please help.... am i doing something very
wrong, am i missing something? what is this invalid preprocessing
directive anyway?
