No, they are different because the @GNULIB_XXX@ macros expand to different
values. For example, in string.in.h there are @GNULIB_XXX@ that are 0 in
libposix and may be 1 in other packages.

No, this is wrong. If you hardcode 0:0:0, the slightest backward incompatible
change will break existing linked programs.

nobase_nodist_pkginclude_HEADERS = $(FNMATCH_H) $(FLOAT_H) $(STDDEF_H) ...
