Would be a nice thing - but it dos'nt work ...
If you call this GetEnv you get an error:
"incompatible type for argument 1 of 'GetEnv'"


The other way :
  function GetEnv(name : PChar): PChar; C;

This also not work with the string-conversion from the faq ;-(
Every time I get a empty string from "GetEnv". (I tried it under DOS.)

      ___,
    ((__         o
   ,____)) V E N I


Moment please ... I think I've found a solution:

  Function GetEnv (var Name: __CString__ ): pChar; C;
                   ^^^
You get a warning about incompatible pointers, but it works ...
Please remove this stupid warning and I'm happy. Yes, I know - I can use  
{$W-}, but it's not so elegant ;-)
