[OpenSource_GPS] Linux OSGPS 2.x Makefile

After looking at the .tar file for OSGPS 2.1 it appears that for some reason the all important makefile was not included.  It is in the CVS but since it is small I decided to send it out to the group.

In addition I'd like to wish you all a Merry Christmas and a Happy New Year.

Best regards,

Cliff
