The function std.file.readLink attempts to convert a char[2048] to a char*
implicitly, causing any code calling it to result in a compiler error.

Test Case:

import std.stdio;
import std.file;

void main() {
        string Path = readLink("/proc/self/exe");


/usr/include/d/dmd/phobos/std/file.d(1834): Error: function
core.sys.posix.unistd.readlink (in const(char*), char*, ulong) is not callable
using argument types (const(char*),char[2048LU],ulong)
/usr/include/d/dmd/phobos/std/file.d(1835): Error: cannot implicitly convert
expression (buffer) of type char[2048LU] to char*

Just add a .ptr when calling the core.sys version.

As an unrelated issue, readLink will also truncate without warning if the path
resolves to more than 2047 characters, but I'm not sure if that's worth opening
a separate bug report for.
