9aec500a26 no need for field 'gch' anymore 2014-07-17 14:27:49 -03:00

5a9cc57a5e change in GCObject: instead of being a union, it is now a structure 
with the common header of all collectable objects; union is used
only for conversions. (Goal is to be able to check that the cast
'obj2gco' can have a check to ensure that object being converted
is really a collectable object.). This is the first step in the
change.
