# Create the export list for perl.
# Needed by WIN32 for creating perl.dll
# based on perl_exp.SH in the main perl distribution directory

# 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.

# There is some symbol defined in global.sym and interp.sym
# that does not present in the WIN32 port but there is no easy
# way to find them so I just put a exception list here
