[ARM][PATCH] Make arm_cmse.h C99 compatible

[Andre Vieira (lists)]

Hi all,

This patch makes the arm_cmse.h header file ISO C compliant. We were
using 'typeof' before when we should be using '__typeof__'.
Duplicated cmse-1.c with -std=c99 on the command line to test this.

Ran the cmse tests for arm-none-eabi.

Is this OK for trunk?

Cheers,
Andre
