Subject: [PATCH 05/10] Allow old-style initializers in derived types
This allows simple declarations in derived types and structures, such as:
LOGICAL*1 NIL /0/
Only single value expressions are allowed at the moment.
Use -fdec-old-init to enable. Also enabled by -fdec.

From 786869fd62813e80da9b6545a295d53c36275c19 Mon Sep 17 00:00:00 2001
From: Mark Eggleston <markeggleston@gcc.gnu.org>
Date: Fri, 22 Jan 2021 13:12:14 +0000
Subject: [PATCH 06/10] Allow string length and kind to be specified on a per
variable basis.
This allows kind/length to be mixed with array specification in
declarations.
e.g.
INTEGER*4 x*2, y*8
CHARACTER names*20(10)
REAL v(100)*8, vv*4(50)
The per-variable size overrides the kind or length specified for the type.
Use -fdec-override-kind to enable. Also enabled by -fdec.
Note: this feature is a merger of two previously separate features.
Now accepts named constants as kind parameters:
INTEGER A
PARAMETER (A=2)
INTEGER B*(A)
Contributed by Mark Eggleston <mark.eggleston@codethink.com>
Now rejects invalid kind parameters and prints error messages:
INTEGER X*3
caused an internal compiler error.

Subject: [PATCH 02/10] Convert LOGICAL to INTEGER for arithmetic ops, and vice
versa
We allow converting LOGICAL types to INTEGER when doing arithmetic
operations, and converting INTEGER types to LOGICAL for use in
boolean operations.
This feature is enabled with the -flogical-as-integer flag.
Note: using this feature will disable bitwise logical operations enabled by
-fdec.
