Follow-up Comment #1, bug #66343 (group make): These seem to be generated by using the streq() macro:
/* Test if two strings are equal. Is this worthwhile? Should be profiled.
*/
#define streq(a, b) \
((a) == (b) || \
(*(a) == *(b) && (*(a) == '\0' || !strcmp ((a) + 1, (b) + 1))))
The pre-check for a == b may seem naive to the compiler but it's part of a
reasonable optimization so maybe this warning can be pragma-ed out. OTOH the
comment says it may be overkill so maybe the pre-checks are a waste of time
anyway. For all I know a reasonable compiler may generate similar code for
strcmp calls anyway, it's quite a stable and common function.
