source: trunk/abcl/src/org/armedbear/lisp/AutoloadMacro.java @ 12594

Last change on this file since 12594 was 12513, checked in by ehuelsmann, 15 years ago

Remove 'private' keyword to eliminate the Java requirement

for the compiler to generate synthetic accessors: functions that
don't appear in the source but do appear in the class file.
