C/C++ have callbacks too, so for the simple case not that much of a problem,
but when nested procs get involved, it might be hard.


Specially since that under ISO nested procedures passed to other functions as procedure
variables have access to their parents context (this is one of the things
the Borland line doesn't support). IOW, such procedures are not pure
function pointers, but functionpointer + a framepointer.


So the first thing would be to check if nested procedures are passed as
prcvar and if they access parent procedures frames (parameters, vars)
