/*
- This workaround for printf functions using 32-bit time_t after the 64-bit time_t upgrade
- The 32-bit time_t usage is triggered through ROM Newlib functions printf related functions calling __swsetup_r() on
the first call to a particular file pointer (i.e., stdin, stdout, stderr)
- Thus, we call the toolchain version of __swsetup_r() now (before any printf calls are made) to setup all of the
file pointers. Thus, the ROM newlib code will never call the ROM version of __swsetup_r().
- See IDFGH-7728 for more details
