Paul, i just commited r32393 (and made a CMR for v1.8)
can you please give it a try ? in the mean time, i received your email ... sysconf is called directly (e.g. no #ifdef protected) in several other places : $ grep -R sysconf . | grep -v svn | grep -v sysconfdir | grep -v autom4te | grep PAGE | grep -v LARGE ./oshmem/mca/memheap/ptmalloc/malloc.c:# define malloc_getpagesize sysconf(_SC_PAGE_SIZE) ./ompi/mca/pml/base/pml_base_bsend.c: tmp =
