and I concur.  The preceeding results are exactly what we would hope to see.

I actually have the misfortune of working on a MS box.  It's been
years since I worked with the configure script.  Does ./configure
delete all of the .elc files?  If it doesn't, try deleting all of the
gnus *.elc files then run make.

same here.

You could try debugging the compiled code.  You'll only be able to see
function calls but that may be enough.  For example, after returning
from nnheader-insert-file-contents, the current buffer should contain
the text in your categories file.  Even more important, I believe that
the first read statement is erroring so you should see the execution
stack unwind up to the ignore-errors form.

If you still have problems, I can create a new version of
gnus-category-read that prints a message before every statement.
Hopefully, that would help us isolate the problem to a single
statement.
