# arch_spec_Exceptions.mk - Architecture/site-specific makefile fragment
#   for inclusion by packages that use Zoom's Exceptions package.
#
# History:
#   08-Feb-2000  WEB  Extracted from ZMutility/zoom.symbols.mk; updated
#     logic reflecting KAI 3.3+ defaults; moved into Exceptions package
#     (could later be moved into SoftRelTools package, if suffient use)
#   30-May-2002  WEB  Updated logic for post-egcs versions of gcc
