Re: Variable not used error

I use the old machine.e. within that is
-- variables and routines used in safe.e without warning integer check_calls check_calls = 1
Running with programs that use this (both on Windows and Linux) produces
Warning ( not_used ): <0229>:: /home/crylex/euphoria/include/machine.e - local variable 'check_calls' is not used ...
When I came across this I just commented out the two lines referring to check_calls since it is local, not global, and cannot affect anything calling machine.e
I am only a Euphoria user, not involved with the implementation, but would guess that
without warning
is not behaving as it should.
It would also appear that v4 has a more strict definition of usage than v3.
With v3, giving a variable a value was 'using' it. On v4 it appears to be necessary to make proper use of it, not just to set it.
The redundant variable was always there with v3, but it didn't care.
