C libraries *before* we throw the AC_LANG([C++]) switch. This makes
the generated configure script use the C compiler/linker instead of
the C++ compiler/linker when running tests. This avoids errors like
these based on not correctly getting the function signature correct:
conftest.cc:36: error: nonnull argument with out-of-range operand
number (arg 1, operand 2)
This error was causing the configure script to not detect *gettext()
routines and not building and installing the *.mo files. This fixes
the error noted in the bulk build results:

It is small and simple to use but with much power and versatility underneath.
Features include customizable functions, units, arbitrary precision, plotting,
and a graphical interface (GTK+) that uses a one-line fault-tolerant expression
entry (although it supports optional traditional buttons).
