This is used +# by platforms that need non-standard library names. +# Examples: ${VERSION}.so.1.1 on NetBSD, since it needs +# to have a version after the .so, and ${VERSION}.a +# on AIX, since the Tcl shared library needs to have +# a .a extension whereas shared objects for loadable +# extensions have a .so extension.
