Avoid including apr_general.h. The MSVC Resource Compiler truncates macro names at char 31. Since apr_general.h includes apr.h which in turn includes system headers we get warnings or errors with the Resource Compiler with newer system headers (VC10 and later) which have macro names defined with more than 31 chars.
