In such cases, you'd better try to find what you are looking for in the
header files. It's not a C++ keyword, so it can only be a macro defined
by us.

So, by searching for '#define mClass', I found the definition in
commondefs.h:

#define mClass          class dll_export

The macro 'dll_export' expands to something non-empty on MSVC (Visual
Studio) only. This is needed because in their eternal wisdom the M$
people thought it would be wise to mix compiler directives directly into
C++ code.


So for all practical purposes, you can think of mClass being 'class'.
