Defines: strcat()

strcat(s, t) concatenates t on the end of s. There had better be
enough room in the space s points to; strcat has no way to tell.
Note that strcat has to search for the end of s, so if you are doing
a lot of concatenating it may be better to use strmov, e.g.
strmov(strmov(strmov(strmov(s,a),b),c),d)
rather than
strcat(strcat(strcat(strcpy(s,a),b),c),d).
strcat returns the old value of s.
