   sftpd version numbers prior to unification
     1.00 - first, plus some other stuff :)
     1.01 - added the 'stdoutLogAnyway' switch
     1.02 - HCL inetd functionality
     1.03 - modified 959 dropdown messages

     1.07 - recvAllBlock, ignore SIGPIPE, implemented RC_PBSZ_TOO_SMALL,
            RandomSeedSaver improvement
            (chose not to auto-detect 3rd-party problem, because it
            would mean adding more complexity than it deserves)
     1.08 - nonportFail -> xSysError::xsyserror
     1.09 - sftpc 1.20 changes, which hopefully didn't affect sftpd functionality
     1.10 - implemented automatic switch to indirect data mode
