 llvm-3.9 build fails at 12% and then at 98% with error strnlen function
 not found

 to fix:

 in this file

 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.9/llvm-3.9/work/trunk/lib/ObjectYAML/MachOYAML.cpp

 and in this file

 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_llvm-3.9/llvm-3.9/work/trunk/tools/obj2yaml/macho2yaml.cpp


 add this replacement function after <string.h> and build succeeds
  (found an example in the cctools patches):

 {{{
 static size_t
 strnlen(const char *s, size_t maxlen)
 {
         size_t len;

         for (len = 0; len < maxlen; len++, s++) {
                 if (!*s)
                         break;
         }
         return (len);
 }
 }}}
