Finding unnecessary (K&R compat) casts

Seems like a pretty good start. I've tried this

find . -name '*.c' -exec egrep -H '\([[:alnum:]_]+ \*\)[ ]*[[:alnum:]_]+[ 
]*\(' {} \;

and found read_seek and strchr to be the highlights.

I've also seen some suprious casts of function return values to void.
Are you getting rid of those as well?
