Still trying to get the curl_formadd() function
implemented across FreePascal/Delphi/Kylix.

Delphi and Kylix understand something called a
"varargs" directive that allows the function to
be called just as it would be in "C".

But FreePascal takes a slightly different approach,
so I need to declare overloaded versions for each
possible number of arguments.

As far as i can tell, the criteria is something
like this:

1. The first two arguments are always pointers to
   Curl_httppost pointers.

2. Between the second and last arguments is *some*
   number of pairs of arguments, always in the form
   of a flag followed by a value. ( Is this correct? )

3, The last argument is always the "CURLFORM_END"
flag.

So the question is, just how many possible flag/value
pairs can there be? Maybe six? Or maybe five thousand?

There appears to be nineteen flags, but some of them,
like CURLFORM_OBSOLETE and CURLFORM_LASTENTRY would
never be used, while others, like
CURLFORM_COPYCONTENTS
and CURLFORM_PTRCONTENTS would be mutually exclusive.

Using the example from the man page, it looks like
this one has the longest argument list:

curl_formadd(
  &post, &last,
  CURLFORM_COPYNAME, "html_code_with_hole",
  CURLFORM_PTRCONTENTS, htmlbuffer,
  CURLFORM_CONTENTSLENGTH, htmlbufferlength,
  CURLFORM_CONTENTTYPE, "text/html",
  CURLFORM_END);

 - This uses four flag/value pairs for a total of
eleven parameters.

Would there ever be a situation where someone might
need more?

Thanks in advance,
 - Jeff
