Re: BASIN build errors

Hi Doug

I have looked into the problem and indeed the problem is related
to the fact the test system is 64bits.

this problem and just crash or, even worse, give wrong results in this
situation.

Anyway I'll fix this problem but to test it I will need to have
access to the 64bits machine.
