Compilation fails now that the default C++ standard is 17, because the
(rather old) upstream code uses the "register" keyword.
./../src-IL/include/il_manip.h:63:2: error: ISO C++17 does not allow 'register' storage class specifier [-Wregister]
register int m = i & 0x007fffff;
^~~~~~~~~
We could selectively set -std=c++14, but it also seems sufficient to
suppress the warning, so this commit chooses that option.
The nixpkgs-unstable channel's programs.sqlite was used to identify
packages producing exactly one binary, and these automatically added
to their package definitions wherever possible.
continuation of #109595
pkgconfig was aliased in 2018, however, it remained in
all-packages.nix due to its wide usage. This cleans
up the remaining references to pkgs.pkgsconfig and
moves the entry to aliases.nix.
python3Packages.pkgconfig remained unchanged because
it's the canonical name of the upstream package
on pypi.
