Subject: [PATCH 01/16] Default widths for i, f and g format specifiers in
format strings.
Enabled using -fdec.
The behaviour is modelled on the Oracle Fortran compiler. At the time
of writing, the details were available at this URL:
https://docs.oracle.com/cd/E19957-01/805-4939/6j4m0vnc3/index.html#z4000743746d
Addition by Mark Eggleston <mark.eggleston@codethink.com>:
Use -fdec-format-defaults to enable this feature. Also enabled using -fdec.

From 8a5920d930429f91b269d9265323bf2507a6b8e5 Mon Sep 17 00:00:00 2001

Subject: [PATCH 06/16] Allow blank format items in format strings
This has to be written in a slightly verbose manner because GCC 7
defaults to building with -Werror=implicit-fallthrough which prevents
us from just falling through to the default: case.
Test written by: Francisco Redondo Marchena <francisco.marchena@codethink.co.uk>
Use -fdec-blank-format-item to enable. Also enabled by -fdec.

Subject: [PATCH 15/16] Allow automatics in equivalence
If a variable with an automatic attribute appears in an
equivalence statement the storage should be allocated on
the stack.
Note: most of this patch was provided by Jeff Law <law@redhat.com>.

Subject: [PATCH 16/16] Suppress warning with -Wno-overwrite-recursive
The message "Warning: Flag '-fno-automatic' overwrites '-frecursive'" is
output by default when -fno-automatic and -frecursive are used together.
It warns that recursion may be broken, however if all the relavent variables
in the recursive procedure have automatic attributes the warning is
unnecessary so -Wno-overwrite-recursive can be used to suppress it. This
will allow compilation when warnings are regarded as errors.
Suppress warning with -Wno-overwrite-recursive
