From dd1ec1448548beee9b9c6a6b1a627580a087b179 Mon Sep 17 00:00:00 2001

Subject: [PATCH] libply: provide rpmatch where the C library lacks it
rpmatch() is a GNU extension. Building against musl fails with an
implicit declaration, and the call is only used to read a yes or no
answer for a boolean command line option, so a plain first-letter test
covers what the parser needs.
