> simple fix for problem mentioned
> 
> When using WinHttpSendRequest() with an empty string as 'headers' argument and
> -1 as a value for the header length, an INVALID_PARAMETER error is returned.
> 
> add_request_headers() in winhttp/request.c correctly performs a strlen() on the
> headers argument if header length is specified as -1. 
> 
> The problem is that if headers is an empty string, and there is no actual
> header, the search for '\r\n\ fails, the terminating zero is found, and
> add_request_header breaks out of the loop with a FALSE return value.
> 
> Under Windows, this call is successful. 

Please add a testcase before submitting to wine-patches.
