C spec:

>That shouldn't be recommended, because names ending with "_t" are reserved.

Also C spec naming new things:

>_Atomic _Bool

I'm glad to see the C folks have a sense of humor.

The standard reserves several classes of identifiers, "_t" suffix is just one of several rules. Another rule is "All identifiers that begin with an underscore followed by a capital letter or by another underscore" (I should also mention "All external identifiers that begin with an underscore").

That only because bool was usually an old alias to int.. It's defined as alias to _Bool in stdbool.h, highly recommended.

Not all reserved names are reserved for all purposes. _t is reserved only for type names (typedefs), whereas _Atomic and _Bool are keywords.
