* 32-bit shadow functions _wprintf_c89(), _fwprintf_c89(), _swprintf_c89()
* are included here.
* When using the c89 compiler to build 32-bit applications, the size
* of intmax_t is 32-bits, otherwise the size of intmax_t is 64-bits.
* The shadow function uses 32-bit size of intmax_t for j conversion.
* The #pragma redefine_extname in <stdio.h> selects the proper routine
* at compile time for the user application.
* NOTE: the shadow functions only exist in the 32-bit library.
