## #2547 — Sascha Schumann — 2003-06-22T17:13:00+00:00

Currently, PHP uses aclocal of the automake suite to include
    libtool's /usr/share/aclocal/libtool.m4.  This is a trivial
    task which does not require aclocal per se.

    However, extension authors might depend on additional m4
    macros such as AM_PATH_GTK_2_0 which are provided by other
    libraries.  If that is the case, they need aclocal to create
    a proper aclocal.m4 file.

    If you are an extension author and use a m4 macro of your
    favorite package in your extension's config.m4, then please
    speak up now.  Otherwise, PHP will soon stop using aclocal.
