Argument typechecking vs. PRINTF et al

[zben at umcp-cs.UUCP]

 If indeed you would be willing to check number and type of arguments
except for the builtins, why not institute a form of declaration that
requests the compiler NOT to check for certain functions:

PRINTF(?)

or something like it.  The builtins could be declared in .h files with
this attributes, and the facility would be available to any user who
specifically requests it for his function...
