Looks like everything apart from AC_PROG_CC_C99 is part of libtool.m4.

Girgias · 2022-09-09T12:38:15Z

#8514 was an attempt to deal with this IIRC

To make sure that compiler supports C99 before Autoconf 2.69, this was needed. But with Autoconf 2.70 and later the macro is obsolete because the checks are done in AC_PROG_CC and warnings are emitted when building configure script. Fixes part of GH-9483

Please cherry-pick both commits to 8.2 at least as after packaging (for Alpinelinux) this errors pollute logs of every build of PECL packages
