I've got no idea.  As far as I understand f->param_alist has the same
structure as initial-frame-alist.  But if I try to get the values for
top and left with stuff like XCDR (Fassq (Qtop, f->param_alist)), all
I get are (identical) addresses as it seems.  For example
top: 18179347, left 18179347
If I try to dereference those with * I get an error during compile.

BTW, I don't get any output if I try to use macros like XCDR or XCAR
with gdb.  Am I doing something wrong?  As far as I understood the
manual of gdb it should be able to handle those.
