setupapi tests question

[Reece Dunn]

When building the setupapi tests with VC9 and the MSVC headers (Vista
version) after using msvcmaker, I get the following output:

2>------ Build started: Project: setupapi_test, Configuration: Debug
MSVC Headers Win32 ------
2>Linking...
2>misc.obj : error LNK2019: unresolved external symbol _MyFree
referenced in function _test_SetupGetFileCompressionInfo
2>.\Output\Win32_Debug_MSVC_Headers/setupapi_test.exe : fatal error
LNK1120: 1 unresolved externals

Where does MyFree come from?

Why does this work with a Wine/MinGW build and not VC9?

Thanks,
