problem linking pthreads

[juanoctaviooviedo at gmail.com (Juan Oviedo)]

Thanks Joel for your answer, but when I compile, I get an error "undefined
reference to `__errno_location'", even if I use "-lrtemscpu". Supposedly
"__errno_location" is defined in pthread library, is it defined somewhere
else in rtems?

Juan.
