> {{./bootstrap.sh}} is using autoconf to convert {{configure.ac}} into the script {{configure}}, everyone used at installation. However, when one enables all warnings, autoconf reports several [obsolete macros|http://www.gnu.org/software/autoconf/manual/autoconf.html#Obsolete-Macros]. Because the configure.ac of Asterisk includes several other m4, quite a long list of warnings is created. However, just nine statements cause this, see the attached {{asterisk_configure_obsolete.patch}}.
> Two affected m4 were imported from upstream projects:
> * [libcurl…|https://github.com/curl/curl/commits/master/docs/libcurl/libcurl.m4]
> * [ax_pthread…|http://www.gnu.org/software/autoconf-archive/ax_pthread.html]
> Their upstream versions avoid those obsolete macros, already. Because Asterisk is using a patched variant of {{libcurl.m4}}, I attached not a patch but the whole m4. Furthermore, I updated that m4 with all upstream patches as of today.
> All this together avoids the obsolete warnings with autoconf 2.69, which was released in April 2012. Tested on Ubuntu 16.04 LTS.
