Looks good to me. You've missed darwin (ldc only) though, while OSX works on 
both ldc and dmd. Shouldn't X86_64 and D_InlineAsm_X86_64 also be ldc only?

I couldn't find it in gdc's documentation, but I think it uses freebsd, 
darwin and solaris and does not support the capitalized identifiers.

By the way, a neater list of ldc's version identifiers is available at
