Compiling the Kernel

[Brian Densmore]

Ok, trouble in assembly land. My system has the Gas assembler. One of
the compile routines wants as86, and thus crashed the compile. Can I
just make a symlink to the Gas assembler or need to modify the makefile,
or do I need to download the binutils and get as86?

Thanks,
Brian
