>Description:
According to
http://pubs.opengroup.org/onlinepubs/7908799/xsh/limits.h.html
a number of PTHREAD_* implementation limits should be defined
by <limits.h>. They are missing.
>How-To-Repeat:
code inspection, or try to build webkitgtk-1.6.1
>Fix:
add to limits.h, or a header pulled in by it
