[Pw_forum] g95 compilation problem

[Andrea Ferretti]

Hi Silviu,
as far as I understand C_POINTER is a preprocessor macro which is defined 
in f_defs.h, as stems from (fft_scalar.f90, lines 72-75)

     72         !   C_POINTER is defined in include/f_defs.h
     73         !   for 32bit executables, C_POINTER is integer(4)
     74         !   for 64bit executables, C_POINTER is integer(8)

therefore it seems there's something wrong with the gcc precompiler 
producing fft_scalar.F90 ...
while C_POINTER is explicitly written in the .f90 file, it should be 
expanded to the macro value ( integer(kind=4 or 8) ) in the .F90 file,
which seems not to be the case here...
