Getting source code updates and recompiling FB

To download updates made available in the fbc Git repository, you can do a 
pull, either using your preferred graphical Git tool, or in a terminal:

   git pull

To take a look at incoming changes before applying them, do this:

   # Update remote branches
   git fetch

   # Take a look
   gitk --all

   # Everything looks ok? Then merge the remote branch into the current branch To apply the update.
   git merge origin/master

Rebuilding is, most of the time, as easy as as running "make" again. Of 
course, if you used compilation options (like ENABLE_STANDALONE) for the 
build, you have to specify them again this time, unless they are (still) 
set in config.mk.

   make
   # Or If needed:
   make ENABLE_STANDALONE=1

As a special exception, for the DOS build it is necessary to run make clean 
before make to properly rebuild FB after source modules have been renamed 
or deleted. The reason for this is that under DOS/DJGPP the makefile uses 
*.o wildcards to link fbc and archive libfb.a etc., instead of passing the 
explicit .o file names, because it has to obey the command line length 
limitation. If make clean is not run, it may use old left-over object files 
from a previous build. Luckily, we do not rename or delete source files 
often.
