readlink and symlink prototypes [PATCH]

- Subject: readlink and symlink prototypes [PATCH]
- Reply-to: Shaun Jackman <sjackman at gmail dot com>
Since readlink and symlink are standard functions (SUSv3 and others) I
would like to see their prototypes provided by default.
As a general rule, could functions defined by SUSv3 be moved
outside the common #if defined(__CYGWIN__) || defined(__rtems__)
line? If so, I'll trickle in patches as I come across them.
Cheers,
Shaun

* libc/include/sys/unistd.h (readlink, symlink): Provide these
prototypes by default.
* libc/sys/linux/include/unistd.h (readlink): Remove this
prototype.
* libc/sys/linux/sys/unistd.h (readlink, symlink): New
prototypes.
