Compiler Warnings #703
Description
There were/are many compiler warnings, esp. with new versions of gcc. This issue is for coordinating analysis and work to each of them. Some of them are already fixed by (pending) PRs.
The following findings are with current (moving) git version of eggdrop.
11. 64-bit NetBSD 6.1.5 gcc 4.5.3 Tcl 8.6.8 OpenSSL 1.0.1i CFLAGS default
Tested eggdrop version: git commit 713cedf Oct 17 2018

This will be fixed by #548

Same with clean NetBSD 8.0 install (gcc 5.5.0 openssl 1.0.2k).
Some update/install installed a second version of openssl under /usr/pkg, the same path tcl is under.
This will be fixed by #1045
Now for the good part.
