[PATCH] stpcpy comes from Turbo C [BZ #3629]

[DJ Delorie]

I can confirm it's documented in my Turbo C manual from 1987.  There's
no specific information on where they got it from, other than saying
str*() functions _as a group_ are "available on Unix systems."
(and that K&R define strcat() ;)

Of course, Turbo C is an MS-DOS compiler :-)

(for a while it was the dominant MS-DOS compiler)
