        PR/42950
        * libgfortran.h (_POSIX): Define if __MINGW32__ is defined.
        (gfc_printf): Define to gnu_printf for __MINGW32__ case,
        otherwise to __printf__.
        (gfc_strtof,gfc_strtod,gfc_strtold): Define for mingw case
        to POSIX compatible converter functions.
        (runtime_error): Use instead gfc_printf as formatter
        attribute name.
        (runtime_error_at): Likewise.
        (runtime_warning_at): Likewise.
        (st_printf): Likewise.
        * intrinsics/date_and_time.c (localtime_r): Undefine
        possible defined macro.
        (gmtime_r): Likewise.
        * io/read.c (convert_real): Use gfc_strtof, gfc_strtod,
        and gfc_strtold.
