1.1.35 $I or $INCLUDE : Include compiler info

In this form:

{$INCLUDE %xxx%}

where xxx is one of the following:

DATE: Inserts the current date.
FPCTARGET: Inserts the target CPU name. (deprecated, use FPCTARGETCPU)
FPCTARGETCPU: Inserts the target CPU name.
FPCTARGETOS: Inserts the target OS name.
FPCVERSION: Current compiler version number.
FILE: Filename in which the directive is found.
LINE: Linenumer on which the directive is found.
TIME: Current time.

If xxx is none of the above, then it is assumed to be the name of an environment variable. Its value will be fetched. As a reult, this will generate a macro with the value of these things, as if it were a string.

For example, the following program

Program InfoDemo;

Const User = {$I %USER%};

begin
  Write ('This program was compiled at ',{$I %TIME%});
  Writeln (' on ',{$I %DATE%});
  Writeln ('By ',User);
  Writeln ('Compiler version: ',{$I %FPCVERSION%});
  Writeln ('Target CPU: ',{$I %FPCTARGET%});
end.

Creates the following output:

This program was compiled at 17:40:18 on 1998/09/09
