The getenv(3) and unsetenv(3) functions already support this.
This will make it easier to emulate the glibc clearenv() function in ports.

CUPS wants it to be a symlink, and that is probably the most common
printing system.  Bad idea to constantly spam everybody about that!
Antoine already adjusted the file permissions in pkg/cupsd.rc rev. 1.24.

correctly - logically complete that now by removing MLINKS from base;
authors need only to ensure there is an entry in NAME for any function/
util being added. MLINKS will still work, and remain for perl to ease
upgrades;

removing its second parameter and the enum() that provided the
values for said parameter.
The function was only called with the second parameter set to one
value (BM_NONBLOCKING) from the enum(). So just do the right thing.
Similar to changes made in smtpd.
While here remove the pointless third parameter from the fcntl(F_GETFL)
call.
No functional change.

void return types 'return no value'. This is obvious and therefore
unneccessary to mention.
We spare rewind(3)'s sentence because espie@ pointed out that it's a
warning - the function masks a potential error.
This commit also adds a sentence to X509_free clarifying that it's
NULL-safe. This bit was discussed with doug@.

Add /var/spool/output/lpd to mtree(1).
This removes the ability for the daemon group to write directly under
/var/spool/output; though no breakage is expected since this directory was only
supposed to contain line printer spooling directories.
