Urgent: WPLockGDICritical undeclared?

I just downloaded the lates wPDF that was posted a few days ago to compile into the latest WPTools 5, and I get the following error when compiling WPTools:

WPPDFWP: Undeclared identifier: WPLockGDICritical

In this block of code:

{$IFDEF WPTOOLS521} // Possible with WPTools V5.21 or higherprocedure TWPPDFExport._Lock;begin{$IFNDEF NEWGR}  EnterCriticalSection(WPLockGDICritical);  // defined in WPRTEPaint!{$ENDIF}end;

Looks like in WPTools 5.58.1, WPRTEPaint, you changed the the definition.

In 5.54:

WPLockGDICritical : TRTLCriticalSection;

In 5.58.1:

pWPLockGDICritical : ^TRTLCriticalSection;

Please advise on how to correct ASAP!
Thanks,
Eric

I changed the code in WPPDFWP to read as follows... I hope this was the correct fix:

{$IFDEF WPTOOLS521} // Possible with WPTools V5.21 or higher
procedure TWPPDFExport._Lock;
begin
{$IFNDEF NEWGR}
  EnterCriticalSection(pWPLockGDICritical^);  // defined in WPRTEPaint!
{$ENDIF}
end;


procedure TWPPDFExport._UnLock;
begin
{$IFNDEF NEWGR}
  LeaveCriticalSection(pWPLockGDICritical^);
{$ENDIF}
end;
{$ENDIF}

Note the change from "WPLockGDICritical" to "pWPLockGDICritical^" in the two places.
