Impossible to determine endianness

[MechWarrior001]

I'm getting error C1189 when attempting to compile. Build output is as follows:

Code: [Select]

fatal error C1189: #error :  Impossible to determine endianness (Little or Big endian), please contact the author.
What would I need to do to fix this?

Getting the same with Visual Studio 2010 and Windows 7

May someone look at this?
