There is a bug in gcc since 4.3.2 and still not fixed in 8.1.0. Even if __attribute__((format(strftime... is specified for a wrapper function around strftime, gcc still complains about strftime being called from the wrapper with a "non-literal" format argument. See https://gcc.gnu.org/bugzilla/show_bug.cgi?id=39438 This commit adds 'ugly hacks' from that discussion to call strftime() from strftime-formatted wrappers and silence the warnings. Partially resolves ipmitool/ipmitool#23 Signed-off-by: Alexander Amelkin <alexander@amelkin.msk.ru>
