/*
 * 32-bit shadow function _wscanf_c89(), _fwscanf_c89(), _swscanf_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 function only exists in the 32-bit library.
