Subject: more configure fixes to pass with -Wimplicit-int
To: ports@openbsd.org
Cc: kili@openbsd.org
Date: Tue, 6 Jan 2026 15:39:18 +0100

Another round of configure files that break because of -Wimplicit-int
and the script using 'main() { return 0; }'.

gmrun is maintained by kili@ so I cc-ed him.
