Cobol: Include m4/autoconf.m4 for autoconf support.
The COBOL compiler now includes m4/autoconf.m4, likely for improved autoconf integration.
The COBOL compiler now includes the m4/autoconf.m4 file. This likely provides necessary macros and configurations for using autoconf to build the COBOL compiler and related tools. This change addresses PR125503.
In Details
The commit adds m4/autoconf.m4 to the COBOL compiler's build system. This likely integrates autoconf macros for configuration during the build process, potentially for better portability or feature detection. Outside the COBOL frontend, the impact is minimal.
For Context
Autoconf is a tool for automatically configuring software build systems. It tests for the presence of system features and adapts the build process accordingly, making software more portable across different operating systems. The m4 directory typically contains macro definitions used by Autoconf. By including m4/autoconf.m4, the COBOL compiler is enabling autoconf support in its build system.
