Subject: [PATCH] strftime: don't use __THROW
Each use of __THROW would provoke this from gcc-7-to-be:
lib/strftime.c:371:1: warning: '__leaf__' attribute has no effect \
on unit local functions [-Wattributes]
static int iso_week_days (int, int) __THROW;
^~~~~~
* lib/strftime.c (__THROW): Don't define.
Remove each use of __THROW.
* lib/strftime.c (memcpy_lowcase, memcpy_uppcase): Remove __THROW.
(tm_diff, iso_week_days, __strftime_internal): Likewise.
