I shared the code (353 lines) on my google drive:

The module that builds the rd_dirlist structure is omitted, two thirds of the code in dir_sync.c is setup for the BACKUP$START() call and mailbox I/O operations.

I could skip the mailbox I/O by building the backup control structure dynamically (with potentially several hundred input files), but concatenating control blocks of different sizes didn't appeal to me.
