# This script will revert the code back to it's original state before the convertMingw64.sh script was applied.
# In particular, it will:
#   1.) Convert 64 bit constants to 32 bit constants (i.e. LL->L and ULL->UL),
#   2.) Convert formatting in printf/sprintf/fprintf (i.e. %lld->%ld, %llu->%lu, etc).
