Thanks for the explanation of your motivation. I wasn't opposed to
this patch but was curious why it mattered. I'd actually like to go
through the source at some point and find places we're making
unreasonable assumptions about implicit inclusion, and also get rid of
some of the unnecessary implicit inclusions (e.g. stdio.h from libc.h
makes no sense and is probably just there because __lockfile is
declared in a poorly chosen place). But for now I'm happy to accept
this patch as a start.
