initialise dc variable to satisfy old compilers.

Browse Source 
When compiling with -Wall on a machine with an old compiler it gives a false
positive that the dc variable which is a structure of type DISPLAY_COLUMNS
could be used uninitialised. In fact the dc variable's members will always get
set in the case it is used, otherwise it is left uninitialised.
This fix just causes the dc variable's members to always get initialised to 0
at declaration, so the false positive will not get flagged.
