I ran into this same problem in my Cygwin->H8S cross.  Don't know the cause, but the bandaid is simple enough.  Find the "gnu-regex.c" file referenced in the error.  Search for "mempcpy"; you'll find one instance of it in a preprocessor construct something like this:

 #if HAVE_MEMPCOPY
	// Use mempcopy
	// ...
 #else
	// Simulate mempcopy
 #endif

Just change the #if to something like:

 #if 0 //HAVE_MEMPCOPY

and you should be good to go.
