Yeah, another one like this I noticed was autoupdate expanding macros in
which means I can't do things like this:

dnl Can't use AC_TYPE_SIGNAL here because it is obsolete
# Stop using AC_HEADER_STDC here because it is deprecated

(without escaping them, that is)

I'm sure it could be improved to better handle this specific case, though.
