[tex-k] [tlbuild] 2010 builds

[Eddie Kohler]

For what it's worth, I have found it easiest (and most correct) to always cast 
the argument of any ctype function to unsigned char (unless I have an unsigned 
char already).  EOF is rarely encountered in practice, unless you read 
characters one at a time with fgetc(), which I doubt tex does.
