Configuring SPL as SHARED

The config.m4 file that is currently shipping (php5-200401192230)
disallows configuring SPL as a shared module on non-Windows as shown
immediately below. However, no such restriction is given for the
Windows configure (config.w32) shown further on. Having built the
shared version for Windows, it also appears to work just fine. Can
someone enlighten me as to whether SPL can/should be built as a shared
PHP module?

Thanks,
