gcc -E slower in beta 18?

[pchow at isgtec dot com (Philip Chow)]

I just recently had some time to move all my tools from beta 14 to beta18
and I am noticing a dramatic performance degradation for C-preprocessing
of files with gcc -E.

If I have the following command:

gcc -D_WIN32 -E -U__GNUC__ -nostdinc -W3 -GX -G5 -DWIN32 -D__STDC__=0 \
    -D_NTSDK -D_WINDOWS -I/path1 -I/path2 -I/path3 -I/path4 -I/path5  \
    -I/path6 -I/path7 -I/path8 -I/path9 file.c

the command executes 4 times slower in beta18 than beta14.  The above
paths reference mounts to 5 different samba server linked network drives.

I have also noticed the same performance degradation in another version
of cpp compiled for beta14 and beta18.

What has changed between beta14 and beta18 which would cause file/directory
access to be slower?

I was all set to move to beta18 until I noticed the performance degradation.
Everything is better in beta18 except for the above problem - I cannot
afford a 60 second gcc -E versus 15 seconds.
