Have no systems with broken `return' at hand,
That's the fundamental problem. These systems are _ancient_ -- they
all predate C89 -- and they are so old that nobody uses them any more.
As I recall when porting a number of packages to OS/390 and z/OS, all
of configure's conftests failed using "return" (SEGV) and I had to
change them all to "exit"...
Hmm, mainframes? I want to say VMS also uses 'return 1' for success
(or maybe it even needs exit; I'm not the one that has to deal with
our VMS systems). But as I recall VMS doesn't have a POSIX shell
either. Is there any VMS support that anyone is worried about?
Yes, there is a POSIX environment available on the mainframes. It's not
the most stable thing in the world (return from main() shouldn't cause a
SEGV, obviously) but it's possible to do useful work in it. I ported all
of BerkeleyDB, OpenSSL, Cyrus SASL, Heimdal Kerberos, and OpenLDAP, and
it all ran with reasonable performance.
