I frequently compile code that has if statements with empty else
clauses, as the result of macros.  I also like to compile with maximum
warning level in gcc.  Now (2.2.2) I get warnings for this practice
which used to (1.39) pass thru gcc without warning.  Can anything be
done to get rid of this warning without losing all the others?

The warning isn't mentioned in the man page, although it goes away
when I don't use -W (I usually use -Wall).  In addition, since it's a
2-line warning, it's hard to clean up the output with a "grep -v"
filter.  I wrote a filter in C that does the trick, but it's a real
pain to have to deal with this.

Does anyone else see a lot of value in this warning?

% cat gccwarn.c
int a(x)
    int x;
{
    if (x)
        x = 7;
    else;
    return (x);
} /* int a */
% gcc-2.2.2 -v
