Will do.

OK, which gcc should I use?  Can I look up which versions of the tools 
are in use for which versions of RTEMS?  That would help a lot.  (This 
was gcc 3.4.0 from the RTEMS site).

Will do.

I know, it has all the files in it that should be one level lower down.

Right, where the files should be.  That's why I thought something with 
lots of ".." in it was messed up.

Yes, with m4 1.4.2 straight from gnu.org.  All the tools I'm using are 
from the RTEMS website or GNU, and I've had success building things in 
December and last summer (but never MVME5500). If you're willing to 
build gm4 1.4.2 with debugging I've attached a .gdbinit that will tell 
us if the problem is there (sprintf %-349s into 256 bytes on the stack) 
on other hosts but just not causing a core dump.

I'll give up and go to 4.6.2 soon with the Brookhaven patches for 
MVME5500 but I'll try a little more with 4.7.
