[15.2.0 autoupdate on configure.ac

User encounters an m4 error when running autoupdate on configure.ac for binutils 15.2.0, possibly due to autoconf version mismatch.

A user is patching binutils 15.2.0 and encountered an m4 error when running autoupdate on configure.ac, citing a version mismatch between their local autoconf (2.73) and the script’s requirement (2.72). The error message indicates an ‘end of file in string’ from m4, possibly related to macro expansion or quoting issues within the GMP version check logic in configure.ac.

In Details

The user is attempting to run autoupdate on configure.ac for binutils 15.2.0, likely to regenerate the build system files after making modifications. They are using autoconf 2.73, which seems to be incompatible with the version expected by the configure.ac script (possibly requiring autoconf 2.72 or earlier). The m4 utility, invoked by autoupdate, is failing with an 'end of file in string' error during the processing of the GMP version check macro, suggesting a syntax or parsing issue possibly related to quoting or macro expansion within that specific section of the script.

For Context
autoupdate
A tool that updates configure.ac and Makefile.am files to newer versions of autoconf macros and syntax.
configure.ac
The main input file for Autoconf, which describes how to configure the package for a particular system. It's processed by autoconf to generate configure.
m4
A macro processor used by Autoconf to preprocess configure.ac before autoconf generates the configure script. It handles macro definitions and expansions.
GMP
The GNU Multiple Precision Arithmetic Library, a free library for arbitrary-precision arithmetic. Binutils may depend on it for certain operations.
autoconf
A tool that automatically configures source code packages to adapt to nearly any Unix-like operating system. It generates shell scripts to adapt programs to local environment.
