* Remove ancient backward compatibility code from m4/m4.m4.Zack Weinberg2022-07-101-10/+3
| | | | | | | | | We have had AC_PREREQ([2.69]) in our own configure.ac since 2021, and before that it was AC_PREREQ([2.62]) since 2012, so backcompat code for 2.61 is not necessary anymore. Also add logging of the name of each candidate executable and bump the serial number.
* Require GNU M4 1.4.8 or later.Zack Weinberg2022-07-061-3/+11
| | | | | | | | | | | | | | | | | | | | | | | The former minimum version was 1.4.6. 1.4.6 and 1.4.7 do not track the original location of text fed to ‘m4wrap’, which breaks autom4te’s ability to trace macros invoked from _AC_FINALIZE. Right now, the only _user_ visible effect of this is that autoconf running on M4 1.4.6 or 1.4.7 will emit an internal error, instead of the intended warning message, when it processes a configure.ac that neglects to invoke AC_INIT or AC_OUTPUT. Perhaps more importantly, it causes a bunch of scary-sounding failures in our own testsuite, which deliberately doesn’t use AC_OUTPUT sometimes. M4 1.4.6 and 1.4.7 also have bugs in location tracking of macro invocations spread over multiple lines, which, guess what, causes even more testsuite failures. 1.4.8 came out in 2006. As a practical matter, this change to our requirements means that people using macOS *to run autoconf* (not just to run generated configure scripts) cannot use the system-provided m4 anymore. {Free,Net,Open}BSD already don’t ship GNU M4 as their system m4, so users of those OSes should not be affected.
