   \defgroup compat_ina90 <compat/ina90.h>: Compatibility with IAR EWB 3.x

   \code #include <compat/ina90.h> \endcode

   This is an attempt to provide some compatibility with
   header files that come with IAR C, to make porting applications
   between different compilers easier.  No 100% compatibility though.

   \note For actual documentation, please see the IAR manual.
