In the case of aspell, which is where I discovered this issue, 1.5.26 was
using the C++ compiler to do the link (for both the library creation and
eventual program creation).  I know that there are other projects that
mixed C and C++ code and weren't correctly being linked by the C++
compiler -- in fact I reported that issue a few weeks ago.  2.2 is a
definite improvement there.

I tried 2.2 for this issue, though, and no improvement over 1.5.26:

By visual inspection, it doesn't look like the relevant code in libtool.m4
that automatically adds `-library=Cstd -library=Crun' has changed in any
significant manner since 1.5.2X.
