Yes they do. Any current project won't bother with K&R. The handful of older 
projects that still have K&R and haven't bothered to rip it out (e.g., glibc is 
*still* ripping it out) should have a toolsmith that knows ancient history. 
Really, K&R support should be turned off by default.

Nontrivial yes, but still it's not terribly hard.

In the short term, perhaps we could work around the problem by replacing this:

extern int make_ctrl_char (int) ATTRIBUTE_CONST;

with this:

extern ATTRIBUTE_CONST int make_ctrl_char (int);

and similarly for the other affected declarations.
