- Alter the build settings for compatibility with Xcode 3.2.x up to Xcode 4.5, keeping a base SDK of 10.5 for compatibility for otherwise adding and adjusting settings appropriately

 - Add instructions to the README for Xcode 4 SDK installation.

 BUILDING SEQUEL PRO
 -------------------
 
-Building Sequel Pro should be straightforward, with no external dependencies or use of
-Interface Builder plugins.
+Sequel Pro has no external dependencies or Interface Builder plugins, so building is
+fairly straightforward.
+
+However, we are curently targetting 10.5 as a minimum version (not for much longer!),
+so the Base SDK is set to 10.5 to correctly report warnings.  Xcode 4 does not ship
+with the 10.5 SDK; to install them:
+ 1) Find a copy of Xcode 3.  If you do not have this installed, it is still available
+	from http://adcdownload.apple.com/Developer_Tools/xcode_3.2.6_and_ios_sdk_4.3__final/xcode_3.2.6_and_ios_sdk_4.3.dmg .
+ 2) Install or extract the 10.5 SDK (and the 10.6 SDK for use soon...).  These would normally
+	have been installed to /Developer/SDKs/MacOSX10.5.sdk and MacOSX10.6.sdk .
+ 3) Copy, or symlink them, into <your Xcode.app>/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs .
+
+After performing these steps 10.5- and 10.6-base SDKs should compile correctly (although
+without PPC support).
