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 ?

'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...)
