A program's build could use certain cpp switches for some of its
sources, and other switches for the other sources.  When Gnulib is
compiled, the value could be unrelated to Gnulib, or unrelated to a
particular Gnulib module that is compiled (perhaps some other Gnulib
module needs that for some reason).

(This is one reason why _WIN32_WINNT is in general not a good idea,
IMO.)
