[M3devel] gcc 4.5 status

[Jay K]

Gcc 4.5 complains about a few similar aspects of our trees.
These would all be errors but I hacked the gcc source to make them warnings.


Running cm3 build with gcc 4.5 crashes early in sysutils => PathReprCommon => Text.Length.


I think I'll try to fix up these type issues first.
You can see they aren't all that interesting, either widening an unsigned integer or
changing the signedness but not the width of an integer.

It's likely this checking isn't on by default, but that I enabled it, and that the errors/warnings are true,
 even though my enabling might have been by hacking the #idefs instead of the configure command.


I assume upgrading to gcc 4.5 is considered fairly unilaterly uncontroversially good.
I chose working on it for that reason.
