gambas 1.0 will never be removed from the current Debian stable distribution
(etch), so anybody using an old 1.0 program could continue using etch
forever. For the next Debian stable (lenny) release it would not be
available.

I mean that problems implementing 64 bits support would make you give up and
stay only with 32 bits in the future. I guess that will not happen, but
knowing if you have considered that idea would help .



As for the testd, I just need some testing on all Gambas examples to check

I don't have any 64 bits computer available, so I can not help you with it.
That's one of the reasons I want to send 64 bits gambas to Debian
experimental: to put it availble to more people who could have such access.
