Update of /cvsroot/micomt/mico/include/mico/os-thread
In directory usw-pr-cvs1:/tmp/cvs-serv19868/include/mico/os-thread
Modified Files:
pthreads.h
Log Message:
- made global debug mutex not recursive
- renamed swap16 to swap_16 because of name clash with OpenBSD's swap16 macro
- fixed time service for compilation on *BSD
- removed old gcc related params from configure
- added checking for pthread's symbols in libc_r (needs for FreeBSD, OpenBSD)
- added semaphore implementation based on mutex & condvar (needs for OpenBSD)
it is used on OSes which doesn't provide POSIX implementation and semaphore.h
