If I compare 4.6.0 20100909 with today's GCC build for Tonto 2.3.1's
crystal.F90, one sees in the original dump that the only TRANSPOSE relevant
change is in the line:

       seitz = transpose(self%spacegroup%seitz(:,:,s))

(Older version: Call to _gfortran_transpose_r8, newer one not.) However, when I
try to create an example out of it, it works as it should.
