FB headers need your help. From libzip to Allego to GTK+, they need to be taken care of and updated every now and then. If you can read C and write FB, you can translate headers.
Here's the current status: http://code.google.com/p/freebasic-headers/wiki/HeaderStatus
Pick a library you care about, maybe one that you use in your project, and download their latest stable release. Translate the C headers to FB, manually or with the help of h_2_bi or FB SWIG. This surely is a good day's work, but the FB community will thank you. Post them on the freebasic-headers or fbc trackers, or in the Libraries forum, and sir_mud and me (and everyone who might join in) will make sure the headers will end up in freebasic-headers download packages and future FB releases.
Do you want to form groups? Or work privately? Or have no time to work on this? It's all ok. If you plan on organizing, consider using sir_mud's forum. Or join us in ##freebasic at irc.freenode.net. Do you want to adopt a header and have your name listed as current maintainer? Sure, we can do that.
So, how to grab the current headers directly?

Have fun, and thanks for helping out.
