-# HP-UX needs the .libs directory in the library search path because of a
-# bug in libtool: it will specify libpcre2.so.0 as the dependency of
-# libpcre2posix.so.0, however when it links it tries to link to libpcre2.so.
-# Although they are the same library, the native ld is not happy with this,
-# and starts looking for the libpcre2.so.0 library on its own, which it won't
-# find, because it wasn't listed on the command line. Hence we need to
-# specify libtool's secret library stash: ".libs".
