[Freeciv-Dev] Suggestion: introduce 'bool' type

[Falk Hueffner <falk.hueffner@xxxxxxxxxxxxxxxxxxxxxxxx>]

Hi,

I think it would be a good idea to introduce a 'bool' type, with
constants 'true' and 'false'. This would make some code much more
readable IMHO.

Note C++ already implements this, and the upcoming C standard will,
too.

If nobody objects, I will write a configure test and add it to
shared.h.
