Log message:
	prototype computing paths from the environment variabls that I believe
	the various setups always set; they don't always set PATH, LIB, INCLUDE,
	but they do set roots like MSVCDir, MSDevDir, VSInstalDir, VCInstallDir,
	and PATH, LIB, INCLUDE can be easily computed from those;
	this is not actually active because I go ahead and clear those variables,
	or never run the intaller in the first place
	
	also remove filtering on backends, should enable maybe some more
	cross scenarios
