Oh, and by the way, this patch seems to be required even by true 
Solaris make implementations (e.g. /usr/xpg4/bin/make on Solaris 10).
Without it, some Yacc/Lex related tests fail (the relevant excerpt
from test-suite.log is attached, gzipped).

On the other hand, it's worth noting that, as stated by Ralf here:
 <http://permalink.gmane.org/gmane.comp.sysutils.automake.bugs/4900>
the tests used to work on Solaris 9 make.
