Just started to use Delhi XE4 and found that LongMonthNames wouldn't compile. Error E2003 Undeclared Indentifier 'LongMonthNames'.
Went to XE3 with the same error, Delphi 2009 with no problem.
Just create a new VCL project with only statment S:=LongMonthNames; will give the error. System.SysUtils is used and the definition is there.
Any clue sombody?
