Yes, having just read the 'make' manpage on a Solaris box, I pretty much 
came to this conclusion myself. The Solaris manpage doesn't say that $< is 
invalid in an explicit rule, just warns that it may not be reliable. 
Anyway, since our objective is to make groff build on as many systems as 
possible, perhaps to achieve maximum reliability, we should simply rewrite 
this rule as explicitly as possible, i.e.

        shdeps.sed: shdeps.sh
                $(SHELL) shdeps.sh "$(RT_SEP" "$(SH_SEP)" "$(bindir)" > 
shdeps.sed

The change needs to be made to line 25 of src/arch/misc/Makefile.sub, in 
the groff-1.19.1 source tree. An appropriate patch is attached; to apply 
it, cd to the top groff-1.19.1 source directory, and

        patch -p2 < shdeps.patch

Best regards,
Keith.
