After I stumbled upon the clash (while obfuscating/shrinking the .C src
to a wimpy program of mine: went from 5k to 750 bytes or so and still
compiled), I noticed it seemed out of place to have "int c, size_t n"
when most other prototypes used underscores (e.g., "void *memchr(const
void *_s, int _c, size_t _n);"). No, not anything useful, and not even
good enough for an IOCCC entry, just me horsing around.  :-P

Feel free to keep your STRING.H unmodified if you're smart enough to
not have that problem (or work around it like I did).  :-)
