### Chose some debug configuration options:
# -DDEBUG
#	Turn on really heavy debug output. This is written to 
#	/tmp/debug/screen.{front,back} Look at these files and quote 
#	questionable sections when sending bug-reports to the author.
# -DTMPTEST
#	Change the socket directory to a location that does not interfere
#	with the (suid-root) installed screen version. Use that in
#	combination with -DDEBUG
# -DDUMPSHADOW
#	With shadow-pw screen would never dump core. Use this option if you
#	still want to have a core. Use only for debugging.
# -DFORKDEBUG
#	Swap roles of father and son when forking the SCREEN process. 
#	Useful only for debugging.
