commit 9bf92cb4c805874b8a7cae803329316a504cfce3
Author: Oswald Buddenhagen <o...@users.sf.net>
Date: Sun Jul 28 21:02:57 2019 +0200
fix lots of sign conversion warnings
... by making a lot of objects unsigned, and some signed.
casts which lose precision and change the sign in one go (ssize_t and
time_t to uint on LP64) are made explicit as well.
