Subject: [PATCH] revert cid 10050DD0C8519194AE9 and 100511FC81525949AF7 AT&T
 SVR4 broke 'cc -c -o foo.o foo.c' totally
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

switch to an alternative method of finding out the prototypes
provided in IRC by dalias (thanks); RT says this fixes his
issues on SVR4 – let’s just ignore the ominous message from
cid 1004713D70A5362BACF about needing to be a compile-time
check unless something else pops up, I can’t think of something
that isn’t already covered
