It looks as though it threw away everything I'd typed in when I added an
attachment, & then submitted the empty report. <sigh>

gcc produced extremely confusing error messages, referencing perfectly valid
line:columns, or (under debugging) referencing location in previously #included
header file.  The bug would have been easily recognized if anything had
indicated the correct location, but the messages weren't especially
descriptive.

Instead of pasting them in, I'll try attaching the programs as well, this time.
 See the .c versions & the error messages in the .txt files.  I guess I'm
supposed to post this, then attach?  I'll try it that way.

first offending program

The compiler error output is as follows:
dlt8.c:7:22: error: expected ',' or ';' before numeric constant

Compiler error output for this one puts the error in stdio.h:

Works on the trunk on x86_64-linux-gnu just fine:

I entered a complete description, then tried attaching the
preprocessor output.  It apparently threw away what I'd entered at
that point.  I've re-entered parts of it & attached more stuff.  I
guess I don't see how to attach without submitting?

As shown in other attachments, for me it generated references to other
lines (many lines away in the big program I tried to reduce this to),
& if I removed all earlier lines referencing a location in stdio.h !

I forgot to add when I reentered stuff.  This was from MinGW running
on Windows XP, but got same error messages on a Linux machine (sent it
to someone to check).  gcc --version shows this:
gcc (GCC) 4.5.2
I don't know how to tell what options the gcc was built with; I did
see that your "what we need listed that, but trying to figure it out I
came up with nothing.

Closing as fixed in mainline then.
