# This is a bit of a mess. The problem is that the fftw library can only be
# built for one data format at a time, so if we want both single-precision and
# double-precision versions then we need two source trees. The alternative
# would be two seperate packages, but then there'd be an equally messy
# exclusions list for all the documentation, include files, etc. that the two
# versions share...
