+Subject: [PATCH] configure.ac: fix out-of-tree tests
+
+To reproduce the test failure one needs to run
+configure using absolute path in a directory
+outside source tree. For example:
+
+ $ $(pwd)/../libcdio-paranoia/configure
+ $ make
+ $ make check
+
+This will cause 'native_abs_top_srcdir' to contain wrong path.
+
+It happens because '[]' is an escape in autoconf.
+As a the following configure.ac snippet:
+ [\\/]* | ?:[\\/]* ) # Absolute name.
+gets translated into the following shell code:
+ \\/* | ?:\\/* ) # Absolute name.
+
+The fix is to change quotes from '[]' for a short while.
