    gas/codeview: avoid "shadowing" of glibc function name
    
    While not "index" this time, old enough glibc also has an (unguarded)
    declaration of fileno() in stdio.h, which triggers a "shadows a global
    declaration" warning with our choice of warning level and with at least
    some gcc versions.
