The code based on hardware detection of stack overflows, which is
based on the detection of certain signals (SIGSEGV in particular)
should work also on the *BSD ports, but I do not think it works on
Windows.

Maybe the Windows exception handler (src/c/unixint.d) can be extended
to trap those conditions, but I do not know enough about that
platform.

If this is not possible, the code I inserted for checking stack
overflows explicitely should still work. These are calls to
ecl_cs_check() inserted by the lisp->C compiler, which verify that the
stack limits have not been reached. These calls are inserted when code
is compiled with (OPTIMIZE (SPEED 2)) or higher.
