+ dnl There's a problem in some old linkers with --version-script that
+ dnl can cause linking to fail when you have objects with vtables in
+ dnl libs 3 deep. This is known to happen in netbsd and openbsd with
+ dnl ld 2.11.2.
+ dnl
+ dnl To test for this we need to make some shared libs and
+ dnl unfortunately we can't be sure of the right way to do that. If the
+ dnl first two compiles don't succeed then it looks like the test isn't
+ dnl working and the result is ignored, but if OTOH the first two
+ dnl succeed but the third does not then the bug has been detected and
+ dnl the --version-script flag is dropped.
