Shared objects of extensions during the *nix build are copied to the `modules` directory. It is a practice established since the early days of the PHP build system. Other build systems may have similar concept of "library destination directory". On Windows, they are put into the root build directory. Such directory simplifies collection of the shared extensions during testing, or when running the cli executable at the end of the build process. This change ensures that the directory is consistently created in a single location, for both the primary PHP build process and when utilizing `phpize` within community extensions. The AC_CONFIG_COMMANDS_PRE is executed at the end of the configuration phase, before creating the config.status script, where also build directories and global Makefile are created. The pwd is executed using the recommended $(...) instead of the obsolete backticks. Autoconf automatically locates the proper shell and re-executes the configure script if such case is found that $(...) is not supported (the initial /bin/sh on Solaris 10, for example).
