You used CHAR_BIT above, why not here?

Looks like a good candidate for flex array
Add a new library to make it easier for eal and other libraries to parse
command line arguments.
The first function in this library is one to parse a corelist string
into an array of individual core ids. The function will then return the
total number of cores described in the corelist.
