--- Comment #1 from Mark Millard <marklmi26-fbsd at yahoo.com> ---
With head having dropped gcc 4.2.1 and things like
controlling the gcc bootstrap, the details of how
the problem was reached are going away (once 12 and
11 are no longer supported).

But /usr/src/Makefile.inc1 still uses:

CROSSENV+=      CC="${XCC} ${XCFLAGS}" CXX="${XCXX} ${XCXXFLAGS} ${XCFLAGS}" \
                CPP="${XCPP} ${XCFLAGS}" \
. . .

which still presumes that the C preprocessor involved
will accept all the options that the c compiler would
accept.

But having no alternatives to llvm as what would be
cross built, I doubt head (13 and later) has the issue
any more.
