BUG: ocrad-0.11 build fails on Tiger

[cssdev@…]

ocrad-0.11 fails to build on Tiger, apparently due to gcc 4 C++ changes. I tried the newer 0.12 release, but that encounters the same errors.

Patch bitmap2.cc to avoid compile failure

I've just updated ocrad to 0.12 and it seems to work flawless w/o any patches; thanks nevertheless for the patch! :)

Are you sure that you're using gcc 4? I'm still seeing the same error:

I obviously forgot to install the XCode 2.1 update. Version 0.12 works perfectly fine with the update installed!
