After some investigation, I found that following reasons (both cpp
related) caused the failure of build/installing XFree86:
1. /usr/libexec/cpp now has no predefined symbols like __FreeBSD__,
which makes imake unable to detect OS type automatically.
Following patch may fix it.

2. /usr/libexec/cpp does not accept "-undef" option any more.

With these two patches, I can successfully build/install XFree86 with
gcc-2.95.2.
Hope it helps,
