 So the problem is the exclusion of 'pthread_*' routines from '-lgcc -lgcc_s'
 of GCC 3.4 (or whatever version ships with 6.x) and GCC 4.5 ? or is it
 exclusion of those routines from 'libc' of 9.x and 6.x ?

 Also I've got a diff related to Japanese IM (Canna) support in Emacs from a
 contributor, I'll send another diff for that. So please delay committing the
 new port.
