Subject RE: configure option to specify mmap/shm

Nope.. It does not work (for me).. That's the reason I need to change to to
use SHMGET_ANON.. I was thinking that there'a already a option available to
do such things..

BTW, is it not strange that it picks up APR_USE_SHMEM_SHMGET, but not
APR_USE_SHMEM_SHMGET_ANON and rather decides to select
APR_USE_SHMEM_MMAP_ZERO..

Does MMAP_ZERO not work on your platform? If so we should probably improve
our autoconf test instead of provide override options.
