SDL's Cocoa backend uses the CGDisplayMode API to get refresh rate information about a display mode, but CGDisplayModeGetRefreshRate will return 0 on most non-CRT monitors.
The only way I know of to get correct refresh rate information in OS X is via the CoreVideo DisplayLink API.
I have attached a patch which tries to use the CVDisplayLinkGetNominalOutputVideoRefreshPeriod function if CGDisplayModeGetRefreshRate fails, which fixes display mode refresh rate information on the monitors I tested.
The CVDisplayLink API requires linking with the CoreVideo framework, and the patch updates the various build files to do so.

Now that SDL on iOS requires CoreMotion to be linked, some of the Xcode projects included with the SDL source (such as the iOS tests and the iOS app template) as well as the premake and automake scripts need to be updated.
I've attached a patch which does so. It also fixes the SDL Xcode project to build for 64-bit ARM as well as armv7 by default (or whatever the default ARM targets are for the Xcode version used), which is what the iOS app template expects.
If the EGL extension EGL_KHR_create_context is available, we can use it to
set the core/compatability profile and the minimum OpenGL version.
Use this if it is available to get the context requested by the GL attributes.
I added -Wshadow and then turned it off again because of massive variable shadowing in the blit macros.
Feel free to go through that code and fix these if you want. Just uncomment CheckWarnShadow in configure.in if you want to try this.
Add V=1 to the make command line will show the full commands but by default
we just show the tool-type and the output file. This is generally much easier
on the eye and makes warnings and errors more clearly visible.
