I also haven't noticed (or had reported to me) any similar drop in speed on UNIX systems. You might check my web pages below for a method of dependency tracking which might be better for you; certainly it will avoid any time spent trying to rebuild the makefiles. Obviously this doesn't solve the underlying problem: if you come up with some information on why the NT version is slow you might want to share it with [EMAIL PROTECTED] which is where many of the Windows-knowledgeable GNU make users hang out. -- ------------------------------------------------------------------------------- Paul D.
