This only retains the objecct factory feature, but removes the garbage collector which I have no use for. # Conflicts: # source/CMakeLists.txt

** The particular scheme used here was chosen because it's small.
|
|
**
|
|
** An alternative that will work with any C++ compiler is to use static
|
|
** classes to build these lists at run time. Under Visual C++, doing things
|
|
** that way can require a lot of extra space, which is why I'm doing things
|
|
** this way.
|
|
**
|
|
** In the case of PClass lists (section creg), I orginally used the
|
|
** constructor to do just that, and the code for that still exists if you
|
|
** compile with something other than Visual C++ or GCC.
