I only tag this onto the end of this conversation because it is
probably relevant, but SVN 2011 barfs on my PC whilst building with
the error:

[ 65%] Building CXX object common/CMakeFiles/common.dir/basicframe.cpp.obj
c:/MinGW/src/kicad/common/basicframe.cpp: In member function `void
WinEDA_BasicFrame::GetKicadHelp(wxCommandEvent&)':
c:/MinGW/src/kicad/common/basicframe.cpp:271: error: `GetChars' was
not declared in this scope
c:/MinGW/src/kicad/common/basicframe.cpp:271: warning: unused variable

make[2]: *** [common/CMakeFiles/common.dir/basicframe.cpp.obj] Error 1
make[1]: *** [common/CMakeFiles/common.dir/all] Error 2
make: *** [all] Error 2

SVN 2010 did not have this problem.
