6.3.2 Configuration in the gcc Directory

The gcc directory is configured with an Autoconf-generated script configure. The configure script is generated from configure.ac and aclocal.m4. From the files configure.ac and acconfig.h, Autoheader generates the file config.in. The file cstamp-h.in is used as a timestamp.

• Config Fragments:    Scripts used by configure.
• System Config:    The config.build, config.host, and config.gcc files.
• Configuration Files:    Files created by running configure.
