What is the problem/bug solved by the patch?
Several of the Plugin Managers fails to define the WXMAKINGDLL_PROPGRID Macros this causes warning and results in the build NOT using the precompiled headers.
The binary output after this change should be an exact match of what it was before the change.
But, the build speed should be slightly faster and the warning should be reduced.
The main gain is it it easier for new developers to make a Plugin the correct way.
Because they do NOT have to add a single define statement for the PCH to be properly used in respect to the wxPropertyGrid library. Patch created against the propgrid/debugger branch.
