small test file
run as:
./soundex burroughs ashcraft brc mcknight mcnaught mcknawt
The optimised code produces:
strlen("burroughs")
B620 burroughs
strlen("ashcraft")
A261 ashcraft
strlen("brc")
B620 brc
strlen("mcknight")
M252 mcknight
strlen("mcnaught")
M252 mcnaught
strlen("mcknawt")
M253 mcknawt
The debug code produces:
strlen("burroughs")
B620 burroughs
strlen("ashcraft")
