My point  is that by always writting  the brace on the  same line than
the while,  if, else, for, etc,  and without spaces  between the right
parenthesis,  the intruduction  of an  unwanted semi-colon  would just
jump in one's face and such an error would not pass unnoticed.

     while(condition);{some-code-here}

is valid C code, but not by my style-book. First, it would be written

     while(condition);{
         some-code-here
     }

next per  the ){  rule, it would have been written by reflex as:

     while(condition){
         ;
         some-code-here
     }

In addition, while(must_wait); is illegal by my style-book. This would
have to be written as:

     while(must_wait){
        /* wait */
     }

And:

     for(init;cond;incr_with_side_effect);

would  be  illegal  too.  First,  I've  a  preference  for  the  while
loops. But anyway it would have to be written as:

     for(init;cond;incr){ 
         side_effect;            
     }

or:
     for(init;cond;/*nop*/){
         incr_with_side_effect;
     }

but preferably:

     init;
     while(!cond){
         incr_with_side_effect;
     }

I don't hope  to really have an influence on  the GNU coding standard,
but I believe  that my style is slightly better  than that pretty good
one. At least, it doesn't  let me make silly syntaxtical errors before
the 30th hour of continuous programming.

My style is:

   if(condition){
       statement;
   }



Perhaps, to make it clearer, I should indicate that my tokens are:

    while(        if(           for(           ){       

    dp{           }else{        }else if{      }

    }while(       


not just: while, if, for, do, else, {, }, (, ).
