portability of errno?

Now that gnulib assumes C89 or better, do we still need the code in
strto[dl].c, unicodeio.c, and unsetenv.c that does this?

#ifndef errno
extern int errno;
#endif

Other modules are just blindly including errno.h and blindly using errno,
macro or otherwise.  Are there any platforms this fails on?
