As a result of Android's relatively incomplete locale.h implementation[1], some functions are not defined and some standard structs are lacking fields (e.g. decimal_point, thousand_sep).
This prevents proper cross-compilation using the Android NDK[2] from succeeding.

Attached is a patch which works around the various issues posed by Android's locale.h implementation, mainly involving falling back to default locale values, causing compilation in that department for the author to succeed.
