-Wall on GNU gcc complains about perfectly legal C code that doesn't need 
fixing.  The production of certain messages may rather be an indication that 
the GNU gcc compiler is broken then if one's believes that -Wall has 
anything to do with quality code.  After all, you should see what -Wall on 
the Intel compiler spits out.  It even warns you if it suspects the source 
author's cholesterol is too high.  Hey and why not -W ?   Even then all the 
possible warning messages still aren't turned on.  I've complained 
about -Wparentheses in particular having no business in -Wall as it flags 
several "style" issues.   Assignment in conditional and the misleading 
ambiguous if/else.  The message for the  latter should read "unambiguous 
statements found!!!" as there's nothing ambiguous about any of them in C.
