    Add --with-mailbox-directory=PATH option to configure
    
    Lets builders set a specific path for mailboxes when the defaults
    don't match the system setup

commit dc963f6d676d1735144ff3997c0ab5bf7cc3889f

    Use <paths.h> and _PATH_MAILDIR to find mailboxes if present
    
    Use autoconf to check for paths.h on all systems, instead of
    only including it #ifdef CSRG_BASED
    
    Makes _PATH_MAILDIR the preferred mail directory path on all systems
    if it's defined, falls back to old per-system hardcoded paths if not.
