I still tend to check for it on the basis that I check all other header
files, so I might as well check that one.  There are systems that do not have
sys/types.h.  That way, all header file checks are done the same way.  That
also means that I always check for stdio.h too, which is contrary to the
recommendations, but makes all the header checks the same.
