POSIX 2003 added this feature, and GNU find only implemented
it in 4.2.12 (i.e. cygwin has not had it until 4.2.25-1, since cygwin
was previously at 4.2.11-CVS).  Because it is relatively new,
portable scripts should not rely on its existance yet (wait for
other platforms to catch up to POSIX first).  Also, be aware that
there are security implications when using -exec, for which
-execdir is a better option - read the info pages.

(Re)read http://sources.redhat.com/ml/cygwin-announce/2005-09/msg00002.html
to see what else find/xargs/locate have recently added.
