# This simple program relys on 'global.sym' being up to date
# with all of the global symbols that a dynamicly link library
# might want to access.
#
# Most symbols have a Perl_ prefix because that's what embed.h sticks
# in front of them.  Variations depend on binary compatibility with
# Perl 5.003.
