streqvcmp - compare two strings with an equivalence mapping

#include <your-opts.h>
cc [...] -o outfile infile.c -lopts [...]

int streqvcmp(char const * str1, char const * str2);

Using a character mapping, two strings are compared for "equivalence". Each input character is mapped to a comparison character and the mapped-to characters are compared for the two NUL terminated input strings. This function name is mapped to option_streqvcmp so as to not conflict with the POSIX name space.
