[Lazarus] Two versions

[Santiago A.]

An interesting idea, but probably too hard for a student project, would 
be the capability of using a C library without having to manually create 
the pas file that translates the c header. That is tedious, error prone 
and a mess when the .h changes and we continue to use the wrong .pas and 
strange error creep in.
Also there are a lot of C libraries that are not available to fpc 
because nobody had the time to create the bindings. I know that there is 
h2pas but it is a off line tool and needs a lot of help from the programmer.

A better way could be to hack a C compiler (GCC ?) and use only the 
parser and the first compilation stage to have the symbols related to 
the available functions and structures and create the pas header from 
that information. With such tool we could have almost automatic use of 
any c library...

Of course, hacking an existing C compiler is not a mostly welcome 
prospect for those who like fpc/Lazarus :)
