Well Fellas: Either have the Steering Committee revise the
Invitation to participate in testing; quoted iselectively below.
Or,have a member from the Steering Committe ask me to refrain
from further participation. I, for one, am no longer willing
to be at the receiving end of snide comments from people who
can not admit that, volunteering or not, are talking through 
their hats.

I am over 70 years of age and have come to my expertise (which
is not in compilers) the hard way. I started with plugboards
and worked my way up to real time assembly systems programming
(telephone Central Office switches and dispatching systems).
The proof of any programming effort is for the hardware to
generate the right output to control other hardware or to
be comprehensible by human beings.   

Now to the specifics:

You might not believe it, but I have a router-firewall, a 
MAC (dual 800 Mhz G4's), a Pentium 3 server (four 550 Mhz
Pentium 3 with 2Gbyte error correcting memory an 130 Giga 
byes of SCSI) assorted other machines all running with
software entirely compiled with gcc-4.1 and gcc-4.2. I only
report to gcc.gnu.org what I consider important problems.
In this specific case I just eliminated the __FUNCTION__
part from bug.h (asm-powerpc) and I am writing this with
kernel-2.6.17-rc3 as compiled by the current gcc-4.2 on
the MAC.

Compiling everything but Ada and running the full test
suite now takes 8.5 hours on a ~800 Mhz pentium 3. There
is realy no publicly available Ada source. I, personally
do not care for Java, but some source packages require
it and sun is apparently no coming out with new releases for 
the powerpc series (competition for server sales) I check
the test suite output to see if that particular gcc is to
be my current production compiler for either pentium3 or
powerpc.

I am a user of compilers (not only gcc) and not a compiler
builder. The four or five problems I reported (and caused 
changes in gcc) sofar were not evidenced by the test suite.

I have about 40 Gigabyte of source code (no games, no IRC,
no themes or their engines, no music or downloading software,
as little Java as possible, and no Pascal).  This is really
software for workstation use. 

Regarding __func__ C99 declares it a "predefined identifier"
and "Like keywords, predefined identifiers must no be
defined by programmers." I am not asking that it becomes
part of GCC. however it should made clear that it and 
certainly __FUNCTION__ are no longer supported.

Regarding __LINE__, __FILE__, __DATE__, etc are required
as per Standard C. Again, the GCC community can state
that it is no honoring that particular requiremnt. However,
the GCC comunity can not unilaterally abrogate that
requirement. The trigraphs come to mind. These are 
probably matters for the Steering Committee.
