GB_INIT() and GB_EXIT() are two mandatory exported functions:
- GB_INIT() is called by the interpreter to initialize the component.
- GB_EXIT() is called by the interpreter to uninitialize the component.

GB is a structure (GB_INTERFACE) that is filled by the interpreter with 
the interpreter API when the component is loaded. So the GB symbol must 
be exported too.

Look at the source of any component to see how they are declared.

Another unrelated point now: as soon as I find time, I will tell you 
what to remove and clean-up in your component. Some GSL functions are 
not useful in Gambas (mainly because they already exist in the 
interpreter), so they should not be implemented in the component.
