-Deactivate _invalid_parameter for now, depends on the strsafe crt implementation also in AMD64 branch
-Fix the weekday offset in gmtime
-Offset the year in *ctime by 1900, fix obvious typos
-Set structure packing to char level: without it the 26 character array is 32 characters wide and the string can't be constructed properly because of alignment characters in between (shouldn't be a problem when _UNICODE is defined)
-Test results: awesome, will be integrated soon
