Thanks!  However, I can still see that warning.  I've installed groff
from git HEAD:

	$ git describe 
	1.23.0-1149-g5589bcd18
	$ git log -1 | head
	commit 5589bcd18776c6d236c53226a0ee30506180e6b6

	    Improve font parsing.
	    
	    The usual (for fontforge converted ttf fonts) is to use the RD, ND
	    and NP operators within charstring definitions, however these are
	    just named in the private subrs dictionary so could be assigned
	    any name.


And here's the warning in the man-pages' contrib branch:

	$ make clean
	RM -rf		.tmp
	$ groff --version | head -n1
	GNU groff version 1.23.0.1149-5589
	$ make build-pdf-book -j24 >/dev/null 2>&1
	$ rm .tmp/man-pages-6.7-63-ga4f3afd28.pdf 
	$ make build-pdf-book
	GROPDF		.tmp/man-pages-6.7-63-ga4f3afd28.pdf

Have a lovely night!
