No, I didn't enable any other major or minor modes before testing. I
also ran emacs with -q --no-site-file.
Your theory about it being related to font-lock-mode appears to be
correct, however! I started emacs, loaded the header file, disabled
font-lock-mode, and ran my test again and it behaved as expected
(i.e., it retained all of my undo records). Is font-lock-mode using
up more records (or more record space) than expected? I wonder if
it's also Windows-specific in some way?
