The most recent version I had was 1.5.12, but I downloaded .13 and got 
the same error you did in make check.  This did not show up in .12.

A .def script is only for Windows.

The make install does not touch any symbols file.  I suppose we need to 
add a sed to Makefile.in to disable this.

sed -i '/^check: scripts\/symbols.chk/d' Makefile.in
./configure --prefix=/usr --disable-static
make check
make install
