detecting the linaro toolchain via C/C++ preprocessor

Hi there!

On Linaro gcc 4.6, I am facing an issue due to "long long" integers not being 64 bit as they are on other platforms I'm targeting, which causes different issues, most importantly with printf format strings. I am now circumventing these by using the C/C++ preprocessor in order to choose the right format strings. In order to minimize the necessity for users to manually configure things, I'm wondering if there is a way to detect the Linaro gcc compiler through preprocessor macros. Is this possible?

Thanks.

Best regards,

Isidor
