- Fix the build against modern libpng (do not try to access private data)

- 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 GtkRadiant; "fix" this with a dirty hack
  by casting those "bad" references to a local volatile int variable
- Remove no longer required and no-op -lpthread vs. -pthread patch hunk
- Report operating system and correct compiler version in the About dialog
- When fixing annoying "GtkSpinButton: setting an adjustment with non-zero
  page size is deprecated" warnings, replace find(1) with grep(1) to narrow
  down initial search results and, subsequently, sed(1) furiousness
- Omit port revision bump as the port was BROKEN for quite some time
