Dear George,

Thanks for pointing this out. I've only tested VPATH builds using GNU
make on linux only, and it worked. I don't have Solaris or Mac
machines, so is there anybody who can help me test this patch on
different operating systems other than linux (hopefully using both GNU
make and other make programs)? Thanks!

It is already stated in the `Readme.buildsac' file that `the build
goes best with GNU development tools, specifically the GNU gcc and the
GNU make'. I hope that my patch will at least work with GNU make on
different systems. Hopefully it won't cause problem when using other
make programs.

I really like this feature since I can keep my source tree uncluttered
this, and I don't need to make copies of the source tree (which is big
and has thousands of files) at anytime.


Best regards,
