Neither of these. It's a usage error. 

The function you're using, nextafterf(), is not in the ANSI
standardized subset of library functions, and thus its declaration is
turned invisible in gcc -ansi mode. Adding -O2 -Wall flags to your
compile line would have given you a hint in that direction, warning
about an "implicit declaration of function `nextafterf'".

I.e.: this program of yours cannot be compiled by a strict ANSI C 
compiler like 'gcc -ansi'.
