Bug#1025973: C99 compatibility fixes for pmount

[Florian Weimer <fweimer@redhat.com>]

Package: pmount
Version: 0.9.23-6
Tags: patch

Future compilers (such as Clang 16 and GCC 14) are likely to disable
support for implicit function declarations by default.  This patch
ensures that pmount doesn't stop building for this reason.
