1) variables nrxx, nr[123][x] moved from gvect to grid_dimensions
2) when the FFT descriptor, fdfftp, is presewnt, values contained
in the descriptor are used instead
Beware unintended side effects.

removed, a few REAL transformed into DBLE. Note that my previos statement
about REAL is overblown: REAl(C) is perfectly safe if C is a double precision
complex number. All changes should be safe.

for a bug, before I realized that there were two copies of "gamma_only",
I wasted two more hours to iuse a single value of "gamma_only" (the one
oin control_flags).

Now the input of v_of_rho is the charge density in both real and reciprocal
space (always available within the scf loop); the output is unchanged. This
permits to get rid of one FFT for the calculation of V-Hartree and one for the
calculation of V-XC (\nabla rhr in GGA). Array dimensions removed from the list
of arguments of several routines (they are read from the modules). Unused
variables removed.
2) mix_rho has been modified in order to mix only the fourier components of the
smooth part of the density. The FFTs in the local-TF preconditioning are done
using the coarse mesh (cft3s). The performance of the mixing is almost
unchanged, but the mixing itself is much cheaper. Cleanup of unused variables.
Please, check for posible side effects of these modifications.

conversion to real => DBLE
(including real part of a complex number)
conversion to complex => CMPLX
complex conjugate => CONJG
imaginary part => AIMAG
All functions are uppercase.
CMPLX is preprocessed by f_defs.h and performs an explicit cast:
#define CMPLX(a,b) cmplx(a,b,kind=DP)
This implies that 1) f_defs.h must be included whenever a CMPLX is present,
2) CMPLX should stay in a single line, 3) DP must be defined.
All occurrences of real, float, dreal, dfloat, dconjg, dimag, dcmplx
removed - please do not reintroduce any of them.
Tested only with ifc7 and g95 - beware unintended side effects
Maybe not the best solution (explicit casts everywhere would be better)
but it can be easily changed with a script if the need arises.
The following code might be used to test for possible trouble:
program test_intrinsic
implicit none
integer, parameter :: dp = selected_real_kind(14,200)
real (kind=dp) :: a = 0.123456789012345_dp
real (kind=dp) :: b = 0.987654321098765_dp
complex (kind=dp) :: c = ( 0.123456789012345_dp, 0.987654321098765_dp)
print *, ' A = ', a
print *, ' DBLE(A)= ', DBLE(a)
print *, ' C = ', c
print *, 'CONJG(C)= ', CONJG(c)
print *, 'DBLE(c),AIMAG(C) = ', DBLE(c), AIMAG(c)
print *, 'CMPLX(A,B,kind=dp)= ', CMPLX( a, b, kind=dp)
end program test_intrinsic
Note that CMPLX and REAL without a cast yield single precision numbers on
ifc7 and g95 !!!

correct place (kinds); module "varie" replaced by "control_flags" (not
yet in pwcom, though) - many many files changed.
64-bit cpus (Opteron, maybe Itanium) should now work if __LINUX64 is defined

- ^M removed from pseudo files
- wavefunctions arrais moved to module
wavefunctions_module, common to all codes
this is required to reduce duplicated subroutine
- new lapack subroutine, called from PWCOND,
added to lib/lapack.f lib/lapack_ibm.f

contributed by Adriano Mosca Conte,
added to the repository.
The non collinear code has required
a new module "wavefunctions" containing
"psic" and "evc", that no longer belong
to pwcom.
use: cvs update -d
there's a new example (example13), that is not
yet complete, I'm waiting for the appropriate
pseudopotential from Adriano
