https://svn.lrde.epita.fr/svn/oln/trunk The updates to Milena follow. Index: ChangeLog from Roland Levillain &lt;roland(a)lrde.epita.fr&gt; Improve support for the FreeImagePlus library. * build-aux/freeimageplus.m4: New. Provide the Autoconf macro OLN_WITH_FREEIMAGEPLUS. Inspired by Olena 0.11's macros AC_WITH_CXX_ZLIB and AC_WITH_CXX_FFTW. Use this macro... * configure.ac: ...here, instead of the previous ad hoc solution. Rename the Automake conditional FREE_IMAGE_PLUS as FREEIMAGEPLUS, and adjust it. * Makefile.am (ACLOCAL_AMFLAGS): New. Set it to `-I build-aux' to have aclocal visit build-aux/freeimageplus.m4.
