I am reserving libpthread for development of the new threads library based on KSEs (schedular activations). Search -arch for more info on that if you are interested. libc will have pthread_* stubs. If you want, you could even make links from libpthread.{a,so} to libc_r.{a,so.5} and link with -lpthread. -- Dan Eischen To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-ports" in the body of the message
