None (see
This message is misleading: when patches are actually applied, there are
additional messages saying “applying ‘foo.patch’”.

It does this:

--8<---------------cut here---------------start------------->8---
fixLibtool() {
    sed 's^eval sys_lib_.*search_path=.*^^' < $1 > $1.tmp
    mv $1.tmp $1
--8<---------------cut here---------------end--------------->8---

This is needed on NixOS, where “standard” search paths (/lib, /usr/lib,
etc.) don’t exist.

It’s 1.5.25.  I don't have direct access to the machine, though, only
via NixOS' build farm.
