/*
* compiler/core/exports.c
*
* ExportElmt list set up during parse.
* (not kept in Module data struct)
*
* SetExports runs through type, value & macro defs and sets the
* exported flag accordingly.
*
* The exportsParsed boolean means whether the symbol "EXPORTS"
* was parsed - since if EXPORTS was parsed and the export list
* is empty, NOTHING is exported, otherwise if the "EXPORTS"
* symbol was not parsed (export list is empty) then EVERYTHING
* is exported. If "EXPORTS" was parsed and the list is not
* empty, then mark each item is the list as exported and the
* rest (that are not in the list) as not exported.
