1#
2# Create the export list for perl.
3#
4# Needed by WIN32 and OS/2 for creating perl.dll,
5# and by AIX for creating libperl.a when -Dusershrplib is in effect,
6# and by MacOS Classic.
7#
8# reads global.sym, pp.sym, perlvars.h, intrpvar.h, thrdvar.h, config.h
9# On OS/2 reads miniperl.map and the previous version of perl5.def as well
