[Bug fortran/16222] New: [gfortran] non-integral DO loop variables are unsupported.

["gcc-bugzilla at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Fortran 77 permits and g77 supports non-integral DO loop variables.
This is a "Deleted feature" in Fortran 90/95.  However, gfortran will
need to support the following:


      program cc
      real x, dx
      dx = 0.1e0
      do x = 0.e0, 1.e0, dx
         print*, x
      end do
      end

Environment:
System: FreeBSD c-67-168-59-70.client.comcast.net 5.2-CURRENT FreeBSD 5.2-CURRENT #2: Sat Apr 24 10:33:08 PDT 2004 kargl@c-67-168-59-70.client.comcast.net:/usr/obj/usr/src/sys/HOTRATS i386


	
host: i386-unknown-freebsd5.2
build: i386-unknown-freebsd5.2
target: i386-unknown-freebsd5.2
configured with: ../gcc/configure --prefix=/home/kargl/gcc/work --disable-libmudflap --enable-languages=c,f95

How-To-Repeat:

kargl[217] gfortran -o cc cc.f
 In file cc.f:4

      do x = 0.e0, 1.e0, dx
         1
Error: Loop variable at (1) must be a scalar INTEGER
