In preparation for the deprecation of `stdenv.isX`.
These shorthands are not conducive to cross-compilation because they
hide the platforms.
Darwin might get cross-compilation for which the continued usage of `stdenv.isDarwin` will get in the way
One example of why this is bad and especially affects compiler packages
https://www.github.com/NixOS/nixpkgs/pull/343059
There are too many files to go through manually but a treewide should
get users thinking when they see a `hostPlatform.isX` in a place where it
doesn't make sense.

Prior to August 2023, any config.guess generated by autoconf will
include a hardcoded /usr/bin/uname invocation for FreeBSD on any
architecture other than arm. This clearly doesn't work under nix.
We must then update or otherwise patch each old config.guess.
This "-D__nonnull\\(params\\)=" leads to a compilation failure in e.g.
the configure phase:
configure:21131: gcc -c -D__nonnull\(params\)= conftest.c >&5
<command-line>: warning: ISO C99 requires whitespace after the macro name
<command-line>: error: stray '\' in program
<command-line>: error: expected ',' or ';' before '(' token
<command-line>: error: stray '\' in program
According to the commit this isn't even needed on Linux.
I confirmed that this is an (expectable) glibc-2.34 thing by checking
that
* the issue doesn't occur with gcc 10/11 on a recent glibc-2.33 staging.
* the issue DOES occur in a docker container with Fedora rawhide (which
has glibc 2.34 and gcc 11).
This adds a warning to the top of each “boot” package that reads:
Note: this package is used for bootstrapping fetchurl, and thus cannot
use fetchpatch! All mutable patches (generated by GitHub or cgit) that
are needed here should be included directly in Nixpkgs as files.
This makes it clear to maintainer that they may need to treat this
package a little differently than others. Importantly, we can’t use
fetchpatch here due to using <nix/fetchurl.nix>. To avoid having stale
hashes, we need to include patches that are subject to changing
overtime (for instance, gitweb’s patches contain a version number at
the bottom).
Run-time deps aren't necessarily on the PATH, so we cannot rely on
configure finding it.
N.B. on cross `-z` support is assumed missing, which is an incorrect
assumption.
updatedb could only be run by providing the --output parameter,
because it would use a path inside the nix store as it's database.
The default for --output is now /var/cache/locatedb (the same
as in the NixOS locate service)
Using the upstream patch directly. It's copied in nixpkgs, because:
- fetchpatch isn't usable at this point in bootstrapping,
- the upstream patch creates collisions in NEWS.
This reverts commit 1daf2e26d2, reversing
changes made to c0c50dfcb7.
It seems this is what has been causing all the reliability problems
on Hydra. I'm currently unable to find why it happens, so I'm forced
to revert the update for now. Discussion: #22874.
The strftime test fails with:
NZST-12NZDT,M9.5.0,M4.1.0/3: expected "1970-01-01 13:00:00 +1300 (NZDT)", got "1970-01-01 12:00:00 +1200 (NZST)"
The source in fact marks this test as "ahistorical", so the result on
Darwin might not be incorrect.

- there were many easy merge conflicts
- cc-wrapper needed nontrivial changes
Many other problems might've been created by interaction of the branches,
but stdenv and a few other packages build fine now.
