+2025-02-07 Robert Dubner <rdubner@symas.com>
+ * Modified configure.ac and Makefile.in to notices that MULTISUBDIR=/32 to
+ suppress 32-builds.
+
2025-01-28 Robert Dubner <rdubner@symas.com>
* Remove TRACE1 statements from parser_enter_file and parser_leave_file;
they are incompatible with COPY statements in the DATA DIVISION.
+
2025-01-24 Robert Dubner <rdubner@symas.com>
* Eliminated missing main() error message; we now rely on linker error
* Cleaned up valconv-dupe and charmaps-dupe processing in Make-lang.in
