Subject: [PATCH] (jm_LIST_MOUNTED_FILESYSTEMS) Check for these headers:
 sys/param.h sys/ucred.h sys/mount.h sys/fs_types.h, and make the link-test
 for getfsstat guard #include directives with appropriate #if HAVE_*_H tests
 so that we can detect getfsstat on Apple Darwin1.3.7 systems.

Also fix harmless typo in cache variable name: s/getsstat/getfsstat/.
