There is configure:25389: checking for ISO C99 wchar_t support configure:25399: result: no and configure:25841: checking for XPG2 wchar_t support configure:25851: result: yes configure:25866: checking for enabled wchar_t specializations configure:25868: result: no in the log. The result is: // Define if code specialized for wchar_t should be used. /* #undef _GLIBCXX_USE_WCHAR_T */ These symbols are available in libcygwin: btowc mbrlen mbrtowc mbsinit mbsrtowcs wcrtomb wcscat wcschr wcscmp wcscoll wcscpy wcscspn wcsncat wcsncmp wcsncpy wcspbrk wcsrchr wcsrtombs wcsspn wcsstr wctob wprintf But these symbols are missing: fgetwc fgetws fputwc fputws fwide fwprintf fwscanf getwc getwchar putwc putwchar swprintf swscanf ungetwc vfwprintf vfwscanf vswprintf vswscanf vwprintf vwscanf wcsftime wcstod wcstof wcstok wcstol wcstoul wcsxfrm wscanf Then there is in the libstdc++ configure: dnl At the moment, only enable wchar_t specializations if all the dnl above support is present. There are quite a lot symbols missing.
