stdatomic.h uses undefined type (___wchar_t)

[Daniel Kowalski]

Hello,

I have question regarding fairly recent change in newlib's stdatomic.h (Copied from FreeBSD sources as far as I understand)

Change itself looks good, but one of the types (___wchar_t, with triple underscore) does not exist anywhere in newlib sources. FreeBSD defines it in their _types.h header. 

Is this simple oversight and extra underscore should be dropped or part of some larger change that wasn't fully commited and this type is supposed to be defined?

change in question:
