This is what I use to compile kernel on 9.0-CURRENT/amd64:
CWARNFLAGS= -Wall -Wredundant-decls -Wnested-externs -Wstrict-prototypes \
-Wmissing-prototypes -Wpointer-arith -Winline -Wcast-qual \
-Wno-pointer-sign -D__FreeBSD_cc_version=0 \
-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 body?
