This is what I use to compile kernel on 9.0-CURRENT/amd64:
CC=3D /usr/local/bin/gcc44
CXX=3D /usr/local/bin/g++44
CWARNFLAGS=3D -Wall -Wredundant-decls -Wnested-externs =
-Wstrict-prototypes \
-Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual =
\
-Wno-pointer-sign -D__FreeBSD_cc_version=3D0 \
-Wno-unused-function -Wno-inline -Wno-format \
-Wno-uninitialized -Wno-array-bounds =
-Wno-missing-prototypes
Note that this is GCC 4.4.4, installed from ports. Also, this will not
compile the world - only the kernel. Also, they were a few fixes to =
make
this work; they were not MFC-ed, iirc; removing -Werror altogether =
should
work around these problems.

If you cut off my head, what would I say? Me and my head, or me and my =
