I heard that if you compile something on leopard it wont work in tiger. But i just passed that off as a rumor or a newbie problem.

Is there anything i should know if i try to compile something in leopard but want to run in tiger?

also, i know this part should go into a 'lounge' area but there is none here.
Would it be easy to install leopard on an external HD? preferably w/o destroying the partitions on it? Has anyone tried installing multiple OS on leopard (vista and XP)? It seems like i have to hack around to get it to do so.

Compile against MacOSX10.4u.sdk and pass -mmacosx-version-min=10.4 to gcc, and your code will run on Tiger.
