	Its my pleasure to involve in LibreOffice development, the concept of more liberated encouraged me to resume.

         Hmm, not thought of win32 build issues

         I mean, the present build.pl when creates unxlngi6.pro dir in one of the symlink under rawbuild, it is going to create under git repo also right? Of course
if expected build.pl can put built files some where else,this wont be an issue.

         Can think of 2-3 types of status reports like no.of source files wise, no.of directories wise etc. and give an option to choose/switch one during build.

     Yes, Will work out status tracking with GNU Make only
