[RFC: new flag] was Re: Multiple inclusion of -lnsl -lsocket

[Robert Boehne]

Douglas:

This is the result of strict dependency tracking.  Later version of
Libtool
refrain from removing duplicates in dependencies because this can break
certain software (KDE is an example I believe).  I also have problems
with this, and have been wondering if a flag to turn this explicitly
ON, off by default, would be a better way around this.
You are getting a truncated command line as you will on almost every
OS (Solaris actually has a much greater command line argument limit
than most other systems).  Libtool used to remove all duplicates,
and I would prefer this to be the default behavior, as it seems
that requiring order-dependencies to be retained is a seldom
used feature that causes problems like yours (and mine).

What would the the rest of you thin about adding a flag
--strict-dependencies
(or some such) that would enable the strict dependency retention, which
is off by default?  I could probably whip this up in a week or so.

Thanks,

Robert Boehne
