I cannot do that unilaterally without waiting for René to respond, though. In any case, with only header and footer changes, here is what will appear in 'pu'. Thanks. -- >8 -- From: René Scharfe <l.s.r@xxxxxx> Date: Thu, 4 Aug 2016 23:56:54 +0200 Subject: [PATCH] nedmalloc: work around overzealous GCC 6 warning With GCC 6, the strdup() function is declared with the "nonnull" attribute, stating that it is not allowed to pass a NULL value as parameter. In nedmalloc()'s reimplementation of strdup(), Postel's Law is heeded and NULL parameters are handled gracefully. GCC 6 complains about that now because it thinks that NULL cannot be passed to strdup() anyway. Because the callers in this project of strdup() must be prepared to call any implementation of strdup() supplied by the platform, so it is pointless to pretend that it is OK to call it with NULL. Remove the conditional based on NULL-ness of the input; this squelches the warning. See https://gcc.gnu.org/gcc-6/porting_to.html for details.
