versions fetched from cvs with -D '2006-12-23' work, later ones fail.

For the older version:

board_new() is called from CreateMainWindow()
board_new() calls board_get_type() which creates a GtkType with an
  init function board_class_init()
  board_class_init is then called from GTK and sets up
     callbacks to board_size_request and board_size_allocate
when RunGTK is called, the callbacks to
     board_size_request() and
     board_size_allocate() 
     occur (both are called in that order, twice during startup)

for versions post 23-12-2006:
board_new() is called, board_class_init() is called, but the callbacks
to board_size_request() and board_size_allocate() are never used,
leaving the program with nSize = -1

The working and non-working programs are linked against the same gtk
libraries: gtk+-2.10.6, bu one version is making the callbacks and the
other is not doing so.
