wxWidgets/include/wx/msw/debughlp.h
Dimitri Schoolwerth 80fdcdb90e No changes, synchronised source names that appear commented at the top of files with the actual path to the files.
Fixed commented names (path, filename, and extension) of files in include/ and src/. Prepended the names in src/ with "src/" everywhere, while starting those in include/wx/ with "wx/".

// reasons:
// - VC6 version of imagehlp.h doesn't define it
// - VC7 one does
// - testing for compiler version doesn't work as you can install and use
// the new SDK headers with VC6
