Changes to NSTableView wont compile

[Fred Kiefer]

Hi Pierre,

the dragging changes you made to NSTableView wont compile with gcc 2.93 
or any other compiler that wont allow you to mix declareations and other 
code. To get it working the beginning of the draggingUpdated: method 
should read:

- (unsigned int) draggingUpdated: (id <NSDraggingInfo>) sender
{
  NSPoint p = [self convertPoint: [sender draggingLocation] fromView: nil];
  NSRect newRect;
  NSTableViewDropOperation operation = NSTableViewDropAbove;
  int row;
  int quarterPosition = (p.y - _bounds.origin.y) / _rowHeight * 4.;
  unsigned dragOperation;


I also did notice that other parts of this file do create warnings from 
the gcc, please remove them (tey are mostly unused variables). It would 
be great if all of GNUstep could compile without giving warnings, 
currenlty this is not possible because of the exception handling code, 
but for the rest we should try and get them away.

Cheers
Fred
