There's no reason why they should be stable, they're internal.  Glibc's
<xlocale.h> reads:

--8<---------------cut here---------------start------------->8---
/* Structure for reentrant locale using functions.  This is an
   (almost) opaque type for the user level programs.  The file and
   this data structure is not standardized.  Don't rely on it.  It can
   go away without warning.  */
typedef struct __locale_struct
--8<---------------cut here---------------end--------------->8---

Maybe, until a better solution is found we could use:

  AC_CHECK_MEMBER([struct __locale_struct.__name] ...)

But we should aim for a more robust solution.

Thanks,
