[Freeciv-Dev] (PR#12478) Meta-ticket: C99 and gcc "pedantic" warnings

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=12478 >

In an effort to track down Mike Jing's recent compile error, I thought 
to try adding

   -pedantic -std=c99

to my cflags.  The result is a lot of warnings, most of which I can 
understand as freeciv doing something "bad".

So, I will provide a series of patches to fix some of these problems.
