Without the change -fno-common toolchains like upstream gcc-10
or clang-11+ fail to build simh as:
$ nix build --impure --expr 'with import ~/nm {}; simh.override { stdenv = clang13Stdenv; }'
...

SimH (History Simulator) is a collection of simulators for historically
|
|
significant or just plain interesting computer hardware and software from
|
|
the past. The goal of the project is to create highly portable system
|
|
simulators and to publish them as freeware on the Internet, with freely
|
|
available copies of significant or representative software.
