This line is >80 chars.  Can you wrap it, please?

It might be better to do something like this:

#if defined(SK_BUILD_FOR_ANDROID) || defined(__UCLIBC__) ||
defined(_NEWLIB_VERSION)
# define HAVE_LOCALE_T 0
#else
# define HAVE_LOCALE_T 1
#endif

and then check HAVE_LOCALE_T later to avoid the repetition.

Done.
