Hi. I built GNU sed for Tru64.

It seemed to require:
./configure CFLAGS="-pthread"
Otherwise, there was an unresolved mbtowc_with_lock.
To be more precise:
Does the compiler complain that the "mbtowc_with_lock" function has an
unresolved symbol relating to 'pthreads' ?
or that the symbol "mbtowc_with_lock" is unresolved ?
Perhaps configure.ac can/should do that automatically?
Perhaps this can/should somehow be done more globally, beyond sed?
i.e. I should refer to autoconf mailing list?
'mbtowc_with_lock' comes from the gnulib module 'mbtowc-lock':
https://git.savannah.gnu.org/cgit/gnulib.git/tree/lib/mbtowc-lock.h
I see the file has several #ifdefs for specific systems,
perhaps Tru64 can be added?
Gnulib experts can perhaps answer this better.
(But as you're aware, there's a limited amount of support for older
systems...)
