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 as well
