More help with Crossfire is always welcome.

Having a roadmap or vision is a good idea. Right now mine is to make
sure the game works on my operating system and keep it that way. My
other vision is to make Crossfire more fun, but without any
crystallization that's not very productive.
I have many, many open issues with Crossfire, but I haven't considered
them important enough to dedicate substantial work to them yet. I'd love
to hear your issues so we can start discussing and working on those

The problem with drawing a bright line is that somebody is inevitably
left on the other side. Many working groups have drawn a standard called
C99; we do not have to rigidly adhere to it, but instead of requiring
specific versions of a specific toolchain, we should write portable code
reasonably within a particular standard.

I've seen recommendations to compile C using a C++ compiler. However, if
you refer to Bjarne Stroustrup's authoritative book he admits that
certain incompatibilities exist. C++ is no more standard than C, and C
is just as (maybe even more) portable as C++.

I'm in favor of doing this in the mid-term. We already have a nice
collection of compatability macros that can serve as a crutch for
compilers we do not obey C99.

I'm not exactly sure what this means. I also see no point in replacing
components that have been in service and aren't breaking. I see no harm
in rewriting code, but it'd be a lot more productive to focus on making
the game more fun than fixing what isn't broken.
