Hi Jim,

The new version relies on a configure-time check (m4/getcwd.m4) and
on the lib/getcwd.c replacement function, on systems that don't
work the way the above code requires.

Is there a problem with one of those?
It sounds like you should find this definition

#define __GETCWD_PREFIX rpl_

in config.h on a Cygwin system.
Similarly, building should compile lib/getcwd.c,
which should define rpl_getcwd.
