Subject: [PATCH 0/6] ISOC23: quell warnings on discarding const

From: Michael J Gruber <[email-masked]>

Hi there

Fedora 44 beta (gcc-16.0.1, glibc-2.43) brought some fun new warnings
when building git. In essence, we're not always explicit about
const-ness or lack thereof of certain pointers. Before, strchr()'s
signature which turns const arguments into non-const return values
covered this up. With ISOC23, strchr() and friends return const
pointers.

This little series takes a middle-ground: no new data types (no new
const versions of non-const data types) but more explicit casts.

Michael J Gruber (6):
  do not discard const: the simple cases
  do not discard const: make git-compat-util ISOC23-like
  do not discard const: adjust to non-const data types
  do not discard const: declare const where we stay const
  do not discard const: keep signature
  do not discard const: the ugly truth
