Thanks for the diagnosis; your guess is correct. Apparently OpenSolaris is still 
using the old SunOS /bin/sh, which doesn't support parameter substitution with # 
or % operators, and the test that 'configure' uses for shells (generated by 
Autoconf) doesn't catch this POSIX incompatibility.

I installed the attached patch into gnulib, which should fix this problem when 
grep gets the latest gnulib version. Using traditional 'case' is easier to read 
for this sort of thing anyway.
