    Subject: Re: perldelta.pod 
    
    Here are some diffs to the _11 pods.  I forgot to add perldelta to
    perl.pod though.
    
    And *PLEASE* fix the Artistic License so it no longer has the bogus
    "whomever" misdeclined in the nominative case:
    
        under the copyright of this Package, but belong to whomever generated
        them, and may be sold commercially, and may be aggregated with this
    
    It should obviously be "whoever".

Subject: Look for gettimeofday() in Configure

Files: Configure config_H config_h.SH pp.c

    Subject: perl5.003_11, Should base use of gettimeofday on HAS_GETTIMEOFDAY, not I_SYS_TIME
    
    I've been installing perl5.003_11 on a SCO system that has the TCP/IP runtime
    installed but not the TCP/IP development system.
    
    Unfortunately the <sys/time.h> include file is included in the TCP/IP runtime
    while libsocket.a is in the development system.
    
    This means that pp.c decides to use "gettimeofday" because <sys/time.h> is
    present but I can't link the perl that gets compiled.
    
    So, here's a patch to base the use of "gettimeofday" on "HAS_GETTIMEOFDAY"
    instead of "I_SYS_TIME".  I also took the liberty of removing the special
    case for plan9 (I assume plan9 has <sys/time.h> but no gettimeofday.  Am I
    right?).
