A list of compiler warnings for some truly awful code.


These things look very fixable to me. George is 86, so he remembers a
more traditional C and has forgotten more about making random numbers
than we'll ever know.

I don't think he reads clc, but do you think your tone appropriate?

Yes.

unsigned long t,x,i; static c=0,j=4691;

is an abomination.

Passing the wrong types to printf is a bug.
