CSCI E-92: Application Note 20

strtoull not available
----------------------

strtoull is missing from the CodeWarrior supplied library.  strtoll *is* in
the library.  You can use that function instead.

Another option is to use sscanf as a replacement that also provides good
error checking.  If you are going to use sscanf then for error checking,
you'll need to check the return value and also look at the %n conversion.

You probably also want to read Application Note 3 (AN3): Using formatted
input and output stdio functions (including printf, snprintf, scanf, sscanf)
with 64-bit (i.e., long long) or floating-point values for information on
using sscanf with 64-bit values.
