[mod-security-users] obsolete macros in running build.sh

[mahh m <muh...@gm...>]

Hi,
when I want to install modsecurity 3.0.12, by running build.sh these
warnings are displayed: warning: The macro `AC_TRY_LINK' is obsolete.
warning: The macro `AC_HEADER_STDC' is obsolete
warning: AC_PROG_LEX without either yywrap or noyywrap is obsolete
warning: The macro `AC_TRY_COMPILE' is obsolete

the warnings remain after running "autoupdate".
the version of "autoconf" is 2.71-2 (on ubuntu 22.04).

how can I resolve it?
