- Clang insists that reference cannot be bound to dereferenced null pointer
in well-defined C++ code (that is correct) and evaluates comparisons like
&foo == 0 to false, which breaks NetRadiant; "fix" this with a dirty hack
by casting those "bad" references to a local volatile int variable (since
NetRadiant is based on GtkRadiant 1.5 codebase, this is the same bug that
was fixed in r384239; patches are slightly different though)
- While here, make a comment more accurate, and bump port revision
