I can provide an almost complete aliment in that direction.
The patch provided below is constructed against todays trunk,
and it solves everything except the build step

    build/lib/lplconsole.o(.text+0x9c3): I funktionen "cb_parse_header":
    : undefined reference to `strncmp'

arising at the very last "ls -N -T ....." command. I had no really good
idea as to the best inclusion path to "strncmp()", and therefore I had
to leave the patchwork at that point. Most of you are more clever than
me in this respect.

Please forgive me for intruding,

Mats Erik Andersson
