You're set up for testing !_MB_CAPABLE > after all... The problem with !_MB_CAPABLE is that these targets don't support any kind of locale settings at all and, so far, setlocale just returns the fixed string "C". Thus it seems it doesn't make any sense to expose the POSIX-1.2008 locale functions to !_MB_CAPABLE targets at all, so I propose to disable these functions and their prototypes unless #ifdef _MB_CAPABLE. Thoughts? Thanks, Corinna -- Corinna Vinschen Cygwin Maintainer Red Hat
