= Some packages may need an adaption with GCC 14

Reference: https://gitlab.com/fweimer-rh/fedora-modernc

== Expect (5.45.4)

FTBFS with `configure: error: could not find source file 'pty_.c'`.

Fedora uses [https://src.fedoraproject.org/rpms/expect/blob/rawhide/f/expect-configure-c99.patch a patch], but the patch needs to run autoconf.  For LFS we can just pass `CC="gcc -std=gnu89"` to configure.

== Libxcrypt (4.4.36)

Fails to probe the `<ucontext.h>` header: https://github.com/besser82/libxcrypt/pull/178

It causes `test/explicit-bzero` skipped.  Not a serious issue and we can ignore.

== Bash (5.2.21 + upstream_fixes-1.patch)

=== a. Wrong probing of dup2

https://lists.gnu.org/archive/html/bug-bash/2023-02/msg00000.html

Not really harming, the probing result still happens to be correct. 

=== b. Wrong probing of strtold

https://lists.gnu.org/archive/html/bug-bash/2023-11/msg00104.html

Real issue.  Causing multiple test failures (for e.g. "printf %.4f 1" outputs "0.0000").

Workaround: `bash_cv_strtold_broken=no` (for safety better include it in chapter 6 too, besides chapter 8).
