Subject: fix use of setlocale all over the place ...
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=12173194711abe6205339f350cd9aa2a75acc467;p=rrdtool.git

fix use of setlocale all over the place ...

-    old_locale = setlocale(LC_NUMERIC, "C");
+    old_locale = setlocale(LC_NUMERIC, NULL);
+    setlocale(LC_NUMERIC, "C");

the original version never restored the locale since it held a copy of the
new locale and not the old one despite the name. bug found by  Pawe? 'Reef' Polewicz
