That's very strange because the configure script has

cat << EOF > conftest.f
      program foo
      double complex zdotu, zx(10), zy(10), retval
      integer n, incx, incy
      n = 10
      incx = 1
      incy = 1
      do 10 i = 1, n
        zx(i) = dcmplx (i, 0)
        zy(i) = dcmplx (0, i)
   10 continue
      retval = zdotu (n, zx, incx, zy, incy)
      if (retval .eq. dcmplx (0, 385)) then
        print *, 'succeeded'
      else
        print *, 'failed'
        print *, retval
      endif
      end
EOF

so I don't understand where the leading spaces on the "program foo"
line went.  They are definitely present in my configure.in and the
generated configure file.
