A number of Mac OS X applications target 10.2 and up, now.  Some apps
(macam.sf.net comes to mind) released stuff before then which is broken
on newer Mac OS X, but can be fixed for 10.2.  The 10.2 fixed stuff
will not work on 10.1 or earlier.  Apple provides "cross development"
tools to build for just about every version of Mac OS X.  But most sane
people?  They target 10.2+.  Even though I'm sure on a mailing list
somewhere, someone inside Apple who never seems able to find anything
better to do is whining on some mailing list that doesn't care about
how they're breaking all sorts of ABI, API, and Scary Monkey compat.
Their cries of DOOOOOOOOOOOM go unheeded.  So will yours.
