t/codingstd/check_toxxx.t - checks that the toxxx() functions are passed
unsigned char
# test all files
% prove t/codingstd/check_toxxx.t
# test specific files
% perl t/codingstd/check_toxxx.t src/foo.c include/parrot/bar.h
Checks all C language files to make sure that arguments to the toxxx()
functions are explicitly cast to unsigned char.
