g95 compiler failing

[Nick Papior]

I have tried compiling siesta, in serial, using g95.

The g95 compiler has some very strict syntax checks, thus many errors arise.

arch.make:
SIESTA_ARCH=x86_64-linux-g95
FC=g95
FC_SERIAL=g95
AR=ar
RANLIB=ranlib
SYS=nag
SP_KIND=4
DP_KIND=8
KINDS=$(SP_KIND) $(DP_KIND)

FFLAGS=-O2 -Wall
FFLAGS_DEBUG=-g

LDFLAGS=
COMP_LIBS += libsiestaBLAS.a libsiestaLAPACK.a

There are numerous bugs to be cleared (also bugs in LAPACK and BLAS).

Luckily these errors have not turned up using other compilers, so _only_ those forced to use the g95 are affected.

(thanks to Javier Junquera for reporting this)

The tighter syntax checks by g95 also affect the 4.0 series. Work on a patch is in progress.

The patch supplied by Nick on Sep. 1st will delete the "CONTIGUOUS" keyword from some argument declarations in m_mixing.F90. This is a F2008 feature, not implemented yet in some compilers.

I am keeping the status as "Fix committed" in the trunk (instead of the customary "Fix Released") because otherwise 4.0 and 4.1 users will not see it.
