Subject: readpst: Fix a build with gcc/C23 standard
Origin: upstream, https://github.com/pst-format/libpst/commit/cc600ee98c4ed23b8ab0bc2cf6b6c6e9cb587e89
Bug-Debian: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1097253

The prototype definitions did not match, but earlier gcc (or pre C23)
did not claim an error on it.
