HEAD: Assume C89 in test suite

[Ralf Wildenhues]

Autoconf made the move, I think it's now time that Libtool assume C89 in
its test suite.  OK?

Cheers,
Ralf
        Drop K&R support from testsuite in favor of C89.

        * tests/duplicate_members.at: provide declarations of used
        functions.
        * tests/testsuite.at: Drop unneeded arguments.
        * tests/cdemo/main.c: Assume C89.
        * tests/demo/dlmain.c: Likewise.
