MFC r248672:

2013-03-27T07:58:29Z

Compile contrib/tzcode/stdtime/localtime.c with -fwrapv, since it relies on signed integer overflow wrapping. Otherwise mktime(3) and timegm(3) can hang, in case the timestamp passed in struct tm is not representable in a time_t. Specifically, any timestamp after 2038-01-19 03:14:07, in combination with a 32-bit time_t. Note that it would be better to change the code to not rely on undefined behaviour, but it is contributed code, and it is not entirely trivial to fix the issue properly.

strptime(3) confused July with June with the fr_FR locale.

When parsing the month "juillet" (abbr "jul"), %B recognized it as "juin" (abbr "jui") because the full name of the month names is checked at the same time as the abbrevation. The new behaviour checks the full names first before checking the abbrevation names. PR: kern/141939 Submitted by: Denis Chatelain MFC after: 1 week

Use _pthread_once() rather than _once() for localtime() and gmtime(). These
