-pthread compiles and links a program using Posix threads.
GNU/Linux uses the -pthread option. Solaris' native compiler uses the
-pthreads option, so GCC uses that option as well.
-mthreads for AIX was inherited from Lynx OS. Because most GCC
configurations use -pthread, GNU/Linux uses -pthread and -pthread makes
the type of thread library more obvious, with GCC 3.0 AIX changed to use
The -pthread commandline option changes the behavior of system
header files, links the application with GCC libraries builts for Posix
threads, and links with Posix thread support in system libraries.
