If one does two "nmake clean"s in a row in the athena directory, the second one fails in .\athena\auth\krb5\src\windows\identity\doc. The line $(RMDIR) /s /q $(DOCDIR)\html in .\athena\auth\krb5\src\windows\identity\doc\Makefile should be if exist '$(DOCDIR)/html' $(RMDIR) /s /q $(DOCDIR)\html Is there any reason I shouldn't make this change? Thanks. Kevin
