some problems in using modern_fftpack via Intel Fortran 2017 #8

Hello, jlokimlin! I am trying to apply the modern_fftpack to my code by Intel Fortran 2017 with Visual Studio 2015 community version on Windows 7 64bit, and I encountered some problems：

  1. Multiple PUBLIC statement/attribute declarations in type_FFTpack.f90 is not allowed in Intel Fortran 2017；
  2. The FFT forward transform result differs from the result obtained by the fftpack library in netlib, and the result by netlib fftpack is N scaled of the result data by modern_fftpack;
  3. Access violation error happened in subroutine complex_pass_n_backward about array assignment operation of array ch1 and cc1 while I am trying to use openmp.

Excuse me for my poor English.

I'll look into these.
