Not a bug in gnulib,

but in guile. Gnulib specifically documents that -Wundef is
incompatible with gnulib modules, and that our coding style is
deliberate. -Wundef only catches portability problems for ancient
(non-C89) compilers, and gnulib requires C89 as a bare minimum. While
you are free to use it for the rest of your project, you need to avoid
it while compiling gnulib (or at least ignore the warnings and avoid
-Werror).
The coreutils project demonstrates how to have two different set of
warning flags appended to AM_CFLAGS: a looser set for the gnulib
subdirectory, and a stricter set for the rest of the project.
