Which is exactly what the libtool documentation says.

I suppose libtool could support a new command-line flag to tell it not
to use the release number as part of the SONAME.  Any suggestions for
the name of the flag?

It doesn't seem to be too tricky to implement.  It would amount to
setting release to an empty string before evaluating soname_spec or
the first name in library_names_spec when computing soname, right
after the comment:

	# Get the real and link names of the library.

We should probably have both forms of names (i.e., with and without
release) in library_names and link_names, though.

Any takers?
