/package/host/code.dogmap.org/foreign/ghc-6.8.2+spf+0/conf/gmp/include/gmp.h

Yes, and .depend-BASE before that.  The only difference in .depend-1
is that "stage1/" is prepended.  compiler/parser/cutils.c includes
includes/Rts.h, which includes gmp.h.  So mkdependC puts that
information in .depend-BASE.  I'm sure it doesn't belong there, since
gmp.h isn't part of the GHC source tree, and I guess if it works for
other people, then it must not be there for them (can anyone confirm
that?), but I don't see how it gets filtered out for them.

Do you mean CPPFLAGS and LDFLAGS, without putting anything in
mk/build.mk or specifying --with-gmp-*?  That fails here:

Actually, it would be GHC_CC_OPTS, since it's ghc compiling a C file,
right?  I tried adding the -optc-I flags, etc., to GHC_CC_OPTS in
mk/build.mk, and it gets farther now, but still fails:

This seems to be coming from an invocation of hsc2hs for dependency
generation.  I don't know how to add extra options to that invocation,
since it isn't directly in any of the Makefiles.  But if it works for
everyone else, I shouldn't need to, either...
