Hi, I just discovered your answers [1, 2] on this subject (I'm not registered to the bug-gnulib mailing list). Thanks for the explanations. I take note that Gnulib does not support use of -Wundef.
I just want to add that I find it good practice to avoid evaluating undefined identifiers in #if directives.
In fact, any package which makes good use of Autoconf cannot support -Wundef.
I don't see why. Could you please elaborate? Best regards, Grégoire Sutre [1] http://lists.gnu.org/archive/html/bug-gnulib/2010-01/msg00316.html [2] http://lists.gnu.org/archive/html/bug-gnulib/2010-01/msg00319.html
