FVWM: FVWM2.0.26 & egcs

[Andrew Veliath]

I had the same problem with LinuxMachineDefines and egcs 1.0 about a
month ago or so.  The spec files of the new gccs are different, and
somehow break the Imake preprocessing.  I forgot how I worked around
it, I probably just reinstalled 2.7.2.3 for the meantime.

I just had a quick look.  It seems that when /lib/cpp is called by
itself, it does not get the options listed in the *cpp: section of the
spec file (maybe this is intended).  It receives those options when
called from the gcc driver though.

As a *workaround*, I put the following script as /lib/cpp2:

#! /bin/sh
gcc -E "$@"

Then, in my shell, exported IMAKECPP:

IMAKECPP=/lib/cpp2; export IMAKECPP

Then you should be able to use xmkmf as usual.
