Hi Bill.  The test you made are wrong: you copied the sed command from
`configure.ac', where square brackets need to be quoted.  You should test,
instead, with the sed command you find in `configure'.  Here is the
relevant fragment:

   # Avoid extra blanks.
   required_instantiations=`echo "${enableval}" | sed -e 's/[	 ][	 ]*/ /g' -e 's/[ ]*\([@<>,]\)[ ]*/\1/g' -e 's/>>/> >/g' -e 's/^[ ]//g' -e 's/[ ]$//g'`
   # Check the specified instantiations for validity.
   ac_save_CPPFLAGS="$CPPFLAGS"
   CPPFLAGS="$CPPFLAGS -I${srcdir}"

Please try again your experiments (both on Linux and Solaris) and let
us know what you get.
All the best,

    Roberto
