ok, I found it.  In line 14514 of configure you have this:

  required_instantiations=`echo "${enableval}" | sed -e 's/[	 ][	 ]*/
/g' -e 's/[ ]*\([@<>,]\)[ ]*/\1/g' -e 's/>>/> >/g' -e 's/^[ ]//g' -e
's/[ ]$//g'`

where enableval looks like:

'        Polyhedron @ Grid @ Rational_Box @ BD_Shape<int8_t> @
BD_Shape<mpz_class> @ BD_Shape<mpq_class> @ Octagonal_Shape<mpz_class>
@ Octagonal_Shape<mpq_class> @ Constraints_Product<C_Polyhedron, Grid>
@ Pointset_Powerset<C_Polyhedron> @ Pointset_Powerset<NNC_Polyhedron>'

It is the pattern 's/[ ]*\([@<>,]\)[ ]*/\1/g'.  Comparing solaris and gnu:

Solaris:

echo '> @ B' | sed -e 's/[ ]*\([@<>,]\)[ ]*/\1/g'
>@ B

GNU:

echo '> @ B' | gsed -e 's/[ ]*\([@<>,]\)[ ]*/\1/g'
>@B

notice the extra space. Now the question, it seems the whole point
of this step is to "Avoid extra blank".  Are there blanks you want to keep,
or can you not just remove every blank?

Cheers,

  Peter
