[Audacity-devel] Warnings from recent check-ins

[James C. <cr...@in...>]

These are some compiler warnings from MSVC resulting from recent check 
ins from other platforms.  I resisted the temptation to fix them 
myself.  In one or two cases they are actually a sign of (mild) 
problems, and I think it better that the relevant person review/fix them 
themselves and check their adjusted code into CVS.

No urgency on these.  It's just housekeeping.

signed/unsigned mismatch is usually best fixed with an (int) cast, after 
inspection shows it's not a problem.
