[Qt-interest] Mac OS X Leopard (10.5.x) and 4.5 - Backward compatibility to Tiger (10.4.x) ?

[Dan White]

In the call to "configure", can I specify more than one item in the  
"sdk" option like this :

./configure \
	-prefix . \
	-prefix-install \
	-release \
	-static \
	-fast \
	-largefile \
	-exceptions \
	-accessibility \
	-stl \
	-qt-sql-sqlite \
	-no-qt3support \
	-no-phonon \
	-svg \
	-no-mmx \
	-no-webkit \
	-no-framework \
	-universal \
	-sdk "/Developer/SDKs/MacOSX10.4u.sdk /Developer/SDKs/MacOSX10.5.sdk"

I am building Qt 4.5.0 on a Leopard (10.5.x) box and want my  
applications to run on Tiger (10.4.x) boxen as well.

Thanks.
