Call for testers for pch-branch

[Geoffrey Keating]

The PCH work is now mostly complete, and it would be helpful if it 
could have some wider testing, especially on non-Darwin hosts.  So, if 
you're interested in precompiled headers, or just want to make sure 
that the patches on the branch don't cause regressions on your 
favourite host or target, I encourage you to check out the branch and 
try it.

You can check out and build the branch by doing

cvs -d :pserver:anoncvs@subversions.gnu.org:/cvsroot/gcc co -r 
pch-branch gcc

and then build it using 'configure' and 'make' as usual.

There are three classes of bugs I'm interested in:

- Things that worked on the tree as at pch-merge-20021124, but don't 
work
   on pch-branch;
- Cases where a compilation produces different output depending on 
whether or
   not a PCH was used (including when it crashes when a PCH is used); and
- Whether you found the documentation clear.

I am also interested in reports of successful builds.

I do know that the testcase gcc.dg/pch/inline-1.c fails with -O3 -g, 
it's a testsuite bug, don't worry about it.  Other than that, all the 
gcc.dg/pch testcases should pass.
