Playing around with checkergcc some more, I found that
expand_to_temp_buffer didn't initialize some of the members of the
FILE_BUF it returns. Dunno wether this has any grave consequences,
but I think it's a bad idea just on general principles.
Below is a patch against the origninal 970924 cccp.c which fixes this
(it also includes the previous patch).
