Re: Cygwin List O' Issus (take 2): #1 static runtime libs

[Charles Wilson]

Resolved?

See patch on libtool-patches.  There are a few extensions to that patch 
that could be added, but they will change current behavior -- and will 
affect platforms I can't test on.

So I'm not the one to propose them.  I took the conservative approach 
with the patch -- "do no harm".  It fixes the cygwin/C++ problem, while 
minimally disturbing other architectures and tags.

In the future, other architectures could join cygwin and set
  _LT_AC_TAGVAR(enable_shared_with_static_runtimes, $1)=yes
in various tags.

Further, somebody "in charge" might decide that C should behave more 
like C++ -- in that it should define an
   output_verbose_link_cmd
call
   AC_LIBTOOL_POSTDEP_PREDEP([tagname])
(which would add the "hidden" libs to $postdeps, $predeps, etc), and 
change all link commands (for tag=C) to use
  -nostdlibs
But that's a radical change and not one I'm comfortable making on my own 
-- and AC_LIBTOOL_POSTDEP_PREDEP really should get a shakedown on other 
platforms, restricted to tag=C++, first.

Currently, the patch does the minimum required to solve cygwin's C++ 
problem and not hurt other platforms/tags.  But the infrastructure is 
there to expand to other tags, and platforms.
