Hi Joseph,
I hit the following problem when trying to build a ppc64 Linux kernel
from svn today:
# gcc -Wp,-MD,scripts/basic/.fixdep.d -Wall -Wmissing-prototypes
-Wstrict-prototypes -O2 -fomit-frame-pointer -o scripts/basic/fixdep
scripts/basic/fixdep.c
cc1: error: unrecognized command line option ‘-MD’
Backing this out fixed it:

* gcc.c (cpp_unique_options): Generate -MDX and -MMDX from -MD and
-MMD.
c-family:
* c.opt (MD, MMD): Change to MDX and MMDX.
* c-opts.c (c_common_handle_option): Use OPT_MMD and OPT_MMDX.
fortran:
* lang.opt (MD, MMD): Change to MDX and MMDX.
* cpp.c (gfc_cpp_handle_option): Use OPT_MMD and OPT_MMDX.
