    Ignore them all.  The first three are dubious.  The spec is somewhat
ambiguous (5.16 Stroustrop), but the definite intent is to replicate the
behavior of an if..else clause.  If start is zero, it would take a very
perverse compiler to increment it in this instance.  And you're probably not
using gopher.

    I have no idea what the last warning is, but you're also probably not
using PICS and even if you are, it's just a trace statement.

  Hello there,

  In compiling package w3c-libwww-5.2.8-7, from Redhat 7.1,

  the Compaq C compiler produced the following messages

  1.

  cc: Warning: HTGopher.c, line 343: In this statement, the expression
"start=start?++start:line" modifies the variable "start" more than once
without an intervening sequence point. This behavior is undefined.
(undefvarmod)

  start = start ? ++start : line;

  --------^

  2.

  cc: Warning: HTGopher.c, line 349: In this statement, the expression
"start=start?++start:line" modifies the variable "start" more than once
without an intervening sequence point. This behavior is undefined.
(undefvarmod)

  start = start ? ++start : line;

  --------^

  3.

  cc: Warning: HTGopher.c, line 402: In this statement, the expression
"start=start?++start:line" modifies the variable "start" more than once
without an intervening sequence point. This behavior is undefined.
(undefvarmod)

  start = start ? ++start : line;

  --------^

  4.

  cc: Warning: CSApp.c, line 382: The scalar variable "pCSUser" is fetched
but not initialized. And there may be other such fetches of this variable
that have not been reported in this compilation. (uninit1)

  HTTRACE(PICS_TRACE, "PICS: User \"%s\" not found.\n" _
CSUser_name(pCSUser));

  --------^

  I'm afraid I have no fixes for any of these problems I have found.

  Regards
