Use locale_t, not __locale_t, throughout glibc
<locale.h> is specified to define locale_t in POSIX.1-2008, and so are
all of the headers that define functions that take locale_t arguments.
Under _GNU_SOURCE, the additional headers that define such functions
have also always defined locale_t. Therefore, there is no need to use
__locale_t in public function prototypes, nor in any internal code.
