+# Process this file with automake to produce Makefile.in

+# We use this libcompat to work around problems with LIBOBJ stuff.
+# For example, we need some of the compat files also in tests/ but the
+# suggested way to do this (using the automake option subdir-objects)
+# leads to problems with "make distclean": The distclean target in
+# tests is run before the one src and it removes the deps files of the
+# libobj files which are in src.  Now when it comes to run make in src
+# the icnluded files are gone - bummer.  Instead of try to fix this
+# issue it seems better not to use subdir-objects but build them all
+# into a compat library and always link against that library.  This
+# also avoids the problem that a dependency on LTLIBOBJ is not setup
+# if -- disable-static was used.
+
+# Need to include ../src in addition to top_srcdir because gcrypt.h is
+# a built header.
