description:
Support <pthread_typs.h> on C89 compilers

Clang 5.0.0(svn) reports warnings on <pthread_types.h> for C99 constructs
when used with strict -std=c89.

Restrict designated initializers usage to C99 or newer code.
C89 and C++ will share the same code without extension of designated
initializers.
