It is an interesting idea. Leaving the question aside how it is implemented (through an AC_SUBSTed variable or what else), the main question is: Would some GNU package maintainers want this? I always thought that GNU package maintainers want their entire package to be compiled with the same CFLAGS and CPPFLAGS. Would compiling the gnulib part with options for fewer warnings be OK with you? Paul, Pádraig, Jim, Paul, Akim, Simon, all: what's your opinion? Bruno
