-    $ echo 'int main() {}' | gcc -o /dev/null -static -x c -
-    /usr/lib/gcc/i486-gnu/4.4.5/../../../libcrt.a(malloc.o): In function `_int_free':
-    (.text+0xdc3): warning: warning: madvise is not implemented and will always fail
-
-This is correct, but it does confuse GNU Autoconf, for example, which then
-thinks that static linking is not supported and sets a flag accordingly, which
-luckly no / not many packages use.
-
-*This call does not influence the semantics of the application (except in the
-case of MADV_DONTNEED), but may influence its performance.  The kernel is free
-to ignore the advice.* (`man madvise`), so we may simply want to turn it into a
-no-op in glibc, avoiding the link-time warning.
-
-GCC c5db973fdab3db3e13db575e5650c0bcfd3630f4 (2011-10-17) makes use of this.
-As we now export the symbol (and `MADV_DONTNEED`, too), GCC will no longer
-`munmap` pages, but will keep them mapped for later re-use.  This may increase
-memory usage.  The discussion in [[!message-id
-"20120720162519.734e02eb@spoyarek"]] touches related topics.

-    <tschwinge> youpi: With Roland's fix the situation will be that just using
-      gcc -static doesn't emit the stub warning, but still will do so in case
-      that the source code itself links in madvise.  Is this acceptable for
-      you/Debian/...?
-    <youpi> packages with -Werror will still bug out
-    <youpi> not that I consider -Werror to be a good idea, though :)
-    <tschwinge> youpi: Indeed.  Compiler warnings can be caused by all kinds of
-      things.  -Werror is good for development, but not for releases.
