Subject: [bug#71534] [PATCH] aclocal: support ACLOCAL_PATH correctly on OS/2
Date: Thu, 13 Jun 2024 20:20:38 +0900

A path separator is ';' on OS/2. Therefore, splitting ACLOCAL_PATH with
':' unconditionally is not correct.

* bin/aclocal.in (parse_ACLOCAL_PATH): Use ';' as a path separator on
OS/2.
