I will think some approach, but if you have some idea to share it would be better so I go directly to a good solution. I'm thinking that to feed the parser I'll have to preprocess the string with another parser, and make a string to string conversion by having a set of defines and paths so that #includes and #ifdefs work. But probably I'll need a cache because the generated string will be huge.

The idea of this work is to be able to feed the parser with C headers and automagically get the C bindings done in smalltalk.
