The m4_normalize(m4_expand([...])) simplifies working with a list of
header files. The m4_normalize() is at this point still used in the
php-src config.m4 files because of copy/paste probability to community
extensions where the arguments still need to be done in the old style to
support phpize in PHP-8.3 and earlier. For example:
PHP_INSTALL_HEADERS([ext/dom], m4_normalize([
dom_ce.h
namespace_compat.h
xml_common.h
xpath_callbacks.h
]))
When PHP 8.4 will be the minimum supported PHP version, the headers can
be installed without using m4_normalize() in PECL extensions. For
example:
PHP_INSTALL_HEADERS([ext/dom], [
dom_ce.h
namespace_compat.h
xml_common.h
xpath_callbacks.h
])
