No, there is no list.

The main gotcha I know of is inline assembly being a bit different. Also 
the glue code for LDC hasn't got ``extern(Objective-C)`` implemented 
currently. I don't know about GDC.

Over all, if you are familiar with GCC & Clang, you'll be ok. A lot of 
the flags from dmd have a comparable version (if not split up further) 
in LDC and GDC.
