[PATCH] vasnprintf.c: Avoid warning about unused label

[Jim Meyering]

Hi Bruno,

I saw this warning:

    vasnprintf.c: In function 'vasnprintf':
    vasnprintf.c:4657: warning: label 'overflow' defined but not used

and propose to eliminate it like this:

        vasnprintf.c: Avoid warning about unused label
        * lib/vasnprintf.c (VASNPRINTF) [!USE_SNPRINTF]: Guard the
        "overflow" label definition and associated code with the
        same cpp condition that guards the sole use of that label.

Ok to commit?
