[Bug other/17991] New: [4.0 Regression] Two-process fixincludes broken: pz_mn_name_pat undefined

["aaronavay62 at aaronwl dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This patch appears to have broken two-process fixincludes: 
<http://gcc.gnu.org/ml/gcc-patches/2004-08/msg02301.html>.  When attempting to 
link applyfix.exe, link fails because pz_mn_name_pat is undefined.

The two-process mode is only used for MS-DOS and BeOS, which is probably why 
noone noticed.  I noticed because it appears that, other than this and some 
other soon-to-be-fixed problems, two process fixincludes also works for 
Windows.

The problem is that mn_name_pat was made into an environment variable, which 
are only defined in fixincl.c, which is only included in the fixincl 
executable.  However, it is used in fixlib.c, which is included in the 
applyfix executable in a two-process build.

As I'm not really familiar with fixincludes, I can't say how this should be 
fixed.  It can be worked around by copying the environment variable 
definitions and initializations from fixincl.c to the SEPARATE_FIX_PROC 
section of fixfixes.c, but I'm not sure this is appropriate as applyfix 
doesn't need any of these environment variables otherwise.  Perhaps just this 
single environment variable could be defined.
