Hi
This adds the following option to configure:
--enable-small-memory-footprint
It overrides (using CFLAGS) the following defines to reduce
the overall memory footprint.
MESSAGE_SIZE_MAX=1024*64
MESSAGE_QUEUE_MAX=512
PROCESSOR_COUNT_MAX=16
IPC_REQUEST_SIZE=1024*64
IPC_RESPONSE_SIZE=1024*64
IPC_DISPATCH_SIZE=1024*64
These values *might* need tweeking but they seem OK from some reasonable
usage.
Regards
Angus
