Since this is comp.std.c, I'll redeclare your list in ANSI.

Actually, given a useful set of end-string functions (including the simplest
one, "char *strend(char *)"), I see no need for any of the "cat" functions.
Even the standard strcat(x,y) is just strcpy(strend(x),y), and if the
application was designed properly it probably already has the value of
strend(x) in hand.

As Doug has noted, "str*" is reserved to the implementation.  Thus, the vendor
is free to add any of these to <string.h> as an extension (and would still
have a conforming implementation).  I suppose many implementations will put
strdup() there.
