I ran into an error compiling the trunk on one of our clusters. It appears that a bug in glibc (version 2.5) causes __pthread_cleanup_routine to be defined when pthread.h is included and compiling with -std=gnu99 and -fexceptions.
The obvious fix is for lanl to upgrade either the cluser's gcc (which undoubtedly has a workaround) or glibc. But, seeing OpenMPI can not require c99 (as much as I would like to require c99) it might be a good idea to remove the c99 requirement on hwloc. Any comments? Better ideas?
