BetterC + startsWith

[SrMordred via Digitalmars-d-learn]

//-betterC
import core.stdc.stdio;
import std.algorithm;
void main(){
    printf( "%d\n",startsWith("a","b") );
}

//Fails to compile with betterC, dmd/ldc2 last versions.

Any reason for not work with betterC or should i file the issue ?
(Find this on a bindbc lib, so i think that it may have worked 
previously)
