Issue: can't compile on Arch Linux #304

The build failure(s) come from the fact that the posix frontends currently
use deprecated functions for multi-threading. The offending functions are:
g_thread_create and g_thread_supported, both deprecated since 2.32.
g_thread_create is replaced by g_thread_new and g_thread_supported is no
longer needed at all for glib >= 2.32 threading is automatically initialized
when the program starts.
