static assert bug

NicoHood
Hey guys,
I am not sure if this is the right place to report a bug, but i will try:

I just noticed that in c files the definition for static_assert() is
missing in assert.h

A simple testcase with provided debug information can be found here:
https://gist.github.com/NicoHood/486364ee191313e1a36d91bb33fba9ef

And here is a sump of assert.h for avr if you dont have it in place:
https://gist.github.com/NicoHood/87b6b6b13b3b8c40145a89173d1b91a0

I am using avr-gcc 6.1 and avrlibc 2.0 (all the latest on archlinux).

what is missing is that static_assert() needs to expand to
_Static_assert() for c files (not c++ though).
Similar to this:
#if !defined(__cplusplus) && !defined(static_assert)
#define static_assert _Static_assert
#endif

Cheers,
Nico

Hi Nico,

Officially, bugs should be reported on the bug tracker [1]. However, it
looks like this one has already been reported, some time ago [2]. I'd
like to see this added, myself; perhaps a bit more noise around this
feature will get it :)
