Thanks.  The method

 cmVisualStudioGeneratorOptions
 ::OutputUndefinePreprocessorDefinitions

appears to duplicate a lot of code from

 cmVisualStudioGeneratorOptions
 ::OutputPreprocessorDefinitions

Please factor out and parameterize the common pieces to
avoid the duplication.

Also, the test case appears to undef a macro in a specific
source file and test that it is undefined, but never defines
the macro for the whole target so of course it will never
be defined and the test will always pass.

Thanks,
