Is there any good reason why "gcc -pthread" links in
-lpthead except when -shared is specified?
Also the gcc man page does not match reality.
-pthread
Link a user-threaded process against libc_r instead of libc.
man pthread mentions these libraries but provided no discussion
on if or when you should include them on the command line. Nor
does it mention "-pthread".
LIBRARY
POSIX Threads Library (libpthread, -lpthread)
1:1 Threading Library (libthr, -lthr)
Reentrant C Library (libc_r, -lc_r)
The hacker handbook seems to indicate that you shouldn't need
to use -lpthread or -lc_r.
