Re: gnulib-tool: indicating the presence of gnulib modules

[Bruno Haible]

Following Simon's comments, I backed this out and instead introduce a
macro gl_MODULE_INDICATOR, for use in the module description.


2007-01-08  Bruno Haible  <address@hidden>

        * m4/gnulib-common.m4: New file.
        * gnulib-tool (func_get_autoconf_snippet): Undo last change.
        (func_get_filelist): Add m4/gnulib-common.m4.
