looks like PLD tcsh is also affected
tcsh$ limit -v
limit: No such limit.

bash (from HEAD) seems to overcame the problem by following defines:
#ifdef RLIMIT_VMEM
#  define RLIMIT_VIRTMEMRLIMIT_VMEM
#  define RLIMIT_VMBLKSZ1024
#else
#  ifdef RLIMIT_AS
#    define RLIMIT_VIRTMEMRLIMIT_AS
#    define RLIMIT_VMBLKSZ1024
#  else
#    define RLIMIT_VIRTMEM259
#    define RLIMIT_VMBLKSZ1
#  endif
#endif
