GCC 3.3.2 kernel


From: Craig Dooley <cd5697@xxxxxxxxxx>
Date: Tue, 28 Oct 2003 23:32:49 -0500

Heres a patch that gets the kernel closer to being built with gcc 3.3.2 from 
ports.  The kernel compiles and runs with gcc 2.95 also as of now, but there 
are changes to drivers I cannot test (if_ray and if_wx that i can think of) 
but I think all the changes deal with either string tokenization or multiline 
strings, so I dont think there should be any problems.  The kernel still 
cannot be built with gcc 3.3.2 though.  When using buildkernel, it gets to 
linking kernel.debug and dies with MANY undefined references to puts and 
putchar.  When using config; make depend; make it dies in make depend.  The 
first pass in aic7xxx/aicasm goes fine, but the second pass dies with missing 
headers and sure enough the headers it wants are not in compile/TRAGEDY/usr/
src/sys/...  I'm looking into those.
