I guess that's a secret I could never have found out on my own,
however adding a few extra instructions the jmp.l abs.l instruction
isn't a big deal.  How would I find out if the garbage collector
is running from the assembly code?  preferebly, MCL should set
some gestalt selector and result for this... does ccl::MAKE-WINDOID-WDEF
modify the def-pascal code in some way?

you could do things this way, but resource id's are commonly useed
in resource templates, and as parameters to control manager and
window manager routines pick which WDEF/CDEF/MDEF/LDEF is to be used
automatically. And, since the different managers expect the code
to be contained in a resource,  there is no guarantee that some of
the resource manager calls don't get called on it...
