I'm using IAR Embedded Workbench for ARM (ARM7TDMI-S) and the majority of my work is done using little-endian format. However, I saw in the manual that I can do something like :

__big_endian int i, j;

to declare those two variables as big endian (while the rest of the app as little endian). This seems like a fantastic feature, but when I try to compile, I always get the errror:

Error[Pa002]: the type attribute "__big_endian" is not allowed on this declaration.

The big endian line above is copied directly from the manual, but it does not work. This is a great feature of the compiler and would make life a big easier. Any ideas how to get it working?

I have my language conformance set to 'Allow IAR extensions' on the C/C++ Compiler options tab on the IDE options.
