But it's not a test failure in a release either (and the point of filing a 
bug when fixing it is for users of releases to be able to find fixed bugs 
when searching Bugzilla; anyone using git master should be following 
libc-alpha).  It's build warnings (the functions get the right types 
anyway, being built-in).  The use of -Werror=implicit-function-declaration 
postdates the last release.
