Do you compile your C code with -Wall?  If you don't, why not?

Do  you have a requirement to remove all warnings before shipping?

What do you do with

	x.c:4: warning: suggest parentheses around assignment used as truth  
value

???

If you want this kind of checking in Tcl, you have to make the  
assignment token significantly visually different.  You complain all  
the time about making Tcl "better".  Here is an area that every C  
programer will agree is a "mistake" in C, and you have a chance to  
avoid the same mistake, so why not take advantage of it?
