bug#52260: Fix compilation error in feature/pgtk branch

[Koen van Greevenbroek]

Hi,

I was just trying to compile the latest version of the pgtk branch when
I noticed that commit 901938109f introduced a regression: two empty
switch cases will result in a compilation error. My suggested fix is
the following:

Fix compilation error due to empty switch cases

modified   src/pgtkterm.c
@@ -4276,6 +4276,7 @@ set_fullscreen_state (struct frame *f)
 
     case FULLSCREEN_WIDTH:
     case FULLSCREEN_HEIGHT:
+       ;
       /* Not supported by gtk. Ignore them. */
     }


This fixes the compilation error for me; I don't know if there is a
more idiomatic way of solving this.

Kind regards,
