Uggh. Gnulib doesn't have a replacement <limits.h> at the moment,
because the absolute-header module doesn't always work on a header with
only macros (which is what limits.h is). I guess this is similar to
float.h, another macro-only header; but there we are using
gl_NEXT_HEADERS() in some cases, since at least 'gcc -E -C' is able to
make sense of things when figuring out how to #include_next.
