Description

The AIX C compiler recommended for use with multi-threaded programs is xlc_r (http://www.nersc.gov/nusers/resources/software/ibm/xlc.html), so we should use this instead of xlc in order that, for example, we get a thread-local errno variable rather than just a global one which may be overwritten by other threads.
