Yup. The idea of PJDIR is to enable application to include build.mak 
in its Makefile and build application with ease.

I suspect probably it's because of mount directories in Mingw. So 
"pwd" interprets the directory as /home, while make.exe uses the 
original directory location.

That's a good solution, I've applied this in 
http://www.pjsip.org/trac/ticket/380. Thanks for spotting and fixing
