/** @file
@brief Interfaces for getopt() and getopt_long() work-alike functions.
This code was taken from FreeBSD and slightly modified, mostly to rename
symbols with external linkage to avoid naming conflicts in systems where
there are real getopt()/getopt_long() implementations. Changed to use
fixed-width types to allow code using these interfaces to be consistent
with the rest of the product.
