If the library is just the header, then there is no difference between
the GPL and the LGPL - any app using it would have to include full
sources for any file using that header, so that changes to that header
(the "library") could be made by the end user and applied to their
app.

Unfortunately, the GPL and LGPL do *not* allow you to rely on "the
internet" to provide source code.  If you distribute a binary, *you*
are responsible for guaranteeing that the sources are available (using
the net for that is OK, but it must be a server *you* control).

However, the key issue for inline-math.h is that, in order to comply
even with the LGPL, any app using it would need to distribute its own
sources anyway, so you might as well have GPL'd it.

If it is your source, you can license that explicitly if you want.

You don't have to assign it.  You can instead grant a sublicence to
us, so that we can use it our way without stopping you from using it
your way.  This is what the FSF does too.  Chris - can you check our
legal forms and see if we have such a clause?
