Not to get off topic or anything, but I would love to see a 
shrinkwrapped version of Gambas appear on store shelves someday for 
20 bucks, since (as you say) there's no reason you can't have 
commercial GPL-licensed software.  Linux really began to take off 
when the shrinkwrapped packages started showing up everywhere, and I 
think Gambas could easily do the same.  (But maybe just having a 
Windows version eventually that didn't depend on Cygwin and could be 
included on TheOpenCD and similar projects would be enough.)

No.... "However, when the interpreter is extended to provide 
"bindings" to other facilities (often, but not necessarily, 
libraries), the interpreted program is effectively linked to the 
facilities it uses through these bindings. So if these facilities are 
released under the GPL, the interpreted program that uses them must 
be released in a GPL-compatible way."
