I installed the latest kernel package from Debian (compiled with gcc 4.1),
the corresponding source. I prepared the kernel source build tree as I
would normally do.
I got to the same point and experienced the same failure again, this time
with a slightly different error message from dmesg. I must admit, I'm
almost ready to abandon this venture. It's proving to be more of a hassle
than I can justify for hours billed. It's not looking good.
Maybe some insight on this anyone, before I scrap it all?
during `make kmod_install`:

...I'll keep plugging away at it. Again, I thank in advance all who provide
your assistance.
Many thanks,

Hi Tommy
Here's one thing we've done on our debian testing machines when the
compiler got upgraded before the kernel. It's kind of gross, but
works.
Go ahead and install the older gcc-4.0 package. The gcc symlink
/usr/bin/gcc will still point to the "default" gcc version, and is the
gcc the kernel build system will try to use. You may have some
specific reasons why you can't install gcc-4.0 but there's a pretty
good chance you'll be able to install multiple gcc packages without
problem.
/usr/bin/gcc probably points to /usr/bin/gcc-4.1 on your box. Go
ahead and temporarily make that link point to /usr/bin/gcc-4.0 while
you make the pvfs2.ko module. Probably would be a good idea to reset
the link after you've built pvfs2.ko
The "debian way" to fix this might be to rebuild the debian kernel
package. Not sure if the compiler is an explicit build-dep though.
Either of those approaches work for you?
