>isgraph() is defined in the att C library.

C *library*?  It doesn't seem to be defined in *AT&T's* C library, at
least as of System V Release 3.1; it's a macro, defined in <ctype.h>.

Are you claiming that there really is an "isgraph.o" in
"/.attlib/libc.a", which contains code for an "isgraph()" *function*? 
If so, why is that?

It's also defined in BSD's <ctype.h>, as of 4.3BSD (although, I infer, it's
not defined in the BSD-environment C include files in OSx).  This is,
amusingly enough, similar to the "memory.h" problem - BSD's been picking
things up from S5, and S5's been picking up things from BSD, so neither
one of them is very pure any more....
