Did this work in the past? I don't think we changed this code recently.
Can you run "make check" to make sure this change doesn't break anything?
Thanks

hwloc-1.6.1rc2 fails to build with the Cray compiler

Cray C : Version 8.1.2  Thu Jan 17, 2013  12:18:54

The error message is

  CC       bitmap.lo
CC-147 craycc: ERROR 
  Declaration is incompatible with "int ffsl(long)" (declared at line 526 of
          "/opt/cray/xe-sysroot/4.1.20/usr/include/string.h").

(Yes, there is no line number with the error message.)

This seems to be caused by the fact that the Cray compiler sets __GNUC__, but is not quite compatible. A work-around is to change line 56 of include/private/misc.h from

#elif defined(__GNUC__)

to

#elif defined(__GNUC__) && !defined(_CRAYC)
