I retraced my commands from the terminal, run make CC="gcc -D_FORTIFY_SOURCE=2" again, this time it works. This shows it is already defined: <blockquote><tt>nadon@memsize:~/xorg/src/app/xclock$ gcc -dM -E - < /dev/null | grep FORTIFY</tt><tt> </tt><tt>#define _FORTIFY_SOURCE 2</tt><tt> </tt></blockquote> There does not seem to be any harm in defining for all builds. If it is not supported, it will be ignored. Let me know, and I can create a patch to add this in util-macros. It can be conditionally added using AC_CHECK_DECLS. If it is already define, it won't be added. </body> </html>
