FreeLibrary(GetModuleHandle(…))?

Hi everybody!

Due to <https://bugs.php.net/76443>, I've noticed a few occurrences
where FreeLibrary() is called on a handle retrieved by
GetModuleHandle().  According to the documentation of
GetModuleHandle()[1], these appear to be wrong, since the docs state:

| Retrieves a module handle for the specified module. The module must
| have been loaded by the calling process.

and

| Therefore, do not pass a handle returned by GetModuleHandle to the
| FreeLibrary function.

Could one of the Windows specialists please review these cases, please?
