Hi; please be sure to use the mailing lists, rather than emailing to me

top-posting.  Thx!

Well, there's no difference in this area that I'm aware of between how
make behaves on Windows vs. other platforms.  Make sure that (a) you're
using GNU make and not some other implementation of make, and (b) you're
using more or less the same version of GNU make on your Windows system.

Also GNU make can be created different ways to run on Windows: as part
of Cygwin, or natively using Visual Studio or mingw, etc.

However, as I mentioned in my previous email there's not much else we
can say based on the information you've provided except "yes, it does so
work".

If you want to resolve the issue you'll have to provide useful
information.  For example, the operating system and version of GNU make
you're using, show the command line you invoked, explain which files
exist (with full paths), show the output make generates, and even run
make with the "-d" flag and include the relevant (only!  Not the entire
output!) lines related to make doing the wrong thing.

Also, if the problem happens only on Windows you might consider asking
on the address@hidden mailing list, which is specifically for issues
related to GNU make on Windows.  Some people on that list don't read
this one.
