[Freeciv-Dev] (PR#13450) require stdint.h presence

["Jason Short" <jdorje@xxxxxxxxxxxxxxxxxxxxx>]

<URL: http://bugs.freeciv.org/Ticket/Display.html?id=13450 >

This rather overcomplicated patch requires that stdint.h (included in
C99) is present.  This shouldn't be a problem on any posix systems I
imagine.  I've read that msvc doesn't have stdint but it can easily be
replaced (probably just copied over from glibc).
