Posted on May 17, 2011 at 13:48All of GCC, Keil/ARM, and IAR support C99 at least in so far as having <stdbool.h> and <stdint.h> headers, and these are the compilers directly supported by ST's peripheral and CMSIS libraries.
Moreover the library already uses <stdint.h> which is a C99 header also.
At least a subset of C99 is supported by most compilers, and provision of these headers requires no modification to the compiler (although the stdbool.h would not have an intrinsic underlying _Bool type). For example, I use a third-party implementation of these for VC++ 2008 for compatibility which does not otherwise provide them).
Even if I were not using a C99 compiler, the unnecessary incompatibility would be better avoided.
My real question is how best to report the issue to ST so that it may be improved? I realise that I can fix it myself, but adding modifications to the library makes it cumbersome and error prone integrating future updates.
