(The perl interpreter could be wrong about what the 6096 underlying locale actually is if some C or XS code has called the C library 6097 function L<setlocale(3)> behind its back; calling L</sync_locale> before calling 6098 this macro will update perl's records.) 6099 6100 A call to L</DECLARATION_FOR_LC_NUMERIC_MANIPULATION> must have been made to 6101 declare at compile time a private variable used by this macro.
