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.
