This seems to be the culprit:

./lib/configure.ac--------------------
# Finish things from ../configure.ac.
AC_SUBST([WARN_CFLAGS])
AM_CONDITIONAL(ENABLE_CXX, test "$use_cxx" != "no")
if test "$use_cxx" != "no"; then
  AC_PROG_CXX
fi
-------------------------------------

Running AC_PROG_CXX no matter whether $use_cxx was set makes the error
go away.[1] I have not got a system without C++ compiler, so I
cannot say whether this would break compilation there.

[1] No idea why
AS_IF([test "$use_cxx" != "no"],
  [AC_PROG_CXX])
seems to also run the test unconditionally.
