+
+	Some definitions for Windows LADSPA plug-ins, the LADSPA_plugins-win project. 
+	So far, we don't want all the declarations in config.h.
+
+	Note that MSVC doesn't define fabsf, powf, or sqrtf for C, only C++, 
+	so the GVerb.dsp project has the /TP global compiler option, to 
+	tell it to treat the .c files as .cpp files, per
+	"http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore/html/_core_.2f.tc.2c_2f.tp.asp"
