cpp -traditional broken?

I was wondering why my today's rebuild of XFree86-4-clients
gave me the black-n-white xdm(1) greeting window, upsetting
me a bit.  It turned out to be a problem with recent cpp(1)
version.

The /usr/X11R6/lib/X11/xdm/Xresources file is generated by
cpp(1); on RELENG_4, the following command

	echo '/**/#if FOO' | cpp -P -traditional

gives you "#if FOO" (as expected by the XFree86 build),
while on 5.2-CURRENT it gives you nothing, and results in
missing parts of the Xresources file, i.e., the new cpp(1)
treats '/**/#if' as a preprocessing directive, while the
old cpp(1) version didn't.

This is with system GCC 3.3.3 compiler.  Is this a known
issue?
