Re: Issue to build gorm-1.2.16 with gcc-4.7

[Gregory Casamento]

This is because 4.6 and 4.7 eliminate (correctly) the
class_pose_as(..) function in the objective-c runtime.

The only reason Gorm contains this call is because it overrides the
poseAs: method on NSObject so that it can provide a warning when
poseAs: is used inside Gorm.

This was necessary when use of Chamaelon, the older theming framework
which functioned by using categories and poseAs: to override classes
so that they would assume a different look, was more common.  But now
that the GSTheme framework is standard, this check is no longer
necessary.

It's a minor change to fix this.  I will make another release of Gorm
once the GNA servers come back up.

Thanks, GC
