You mean, complex.  Get it wrong, and our private version is getting
linked and the Guile-2 version left out.  Or we get double-definition
link-time errors.  So we want an autoconf test and so on.

Having our own ly_is_integer variant map to the Guile-2 version
conditionally is simple, and when we do it wrong, there is an obvious
missing symbol at link time.  Or stuff works without complaint.
