When I look at a C compile on Linux (with GCC 4.1.1 or with GCC ToT) on
x86, I see a link line containing:

-lgcc --as-needed -lgcc_s --no-as-needed -lc -lgcc --as-needed -lgcc_s
--no-as-needed

So it looks like GCC is going to use the static libgcc first and include
the shared libgcc_s only if needed, this may be why Linux doesn't have
the same problem as HP-UX with libgomp.   The HP linker that I am using
on IA64 HP-UX doesn't have an --as-needed flag.  I guess I could leave
it out and use -lgcc -lgcc_s on HP-UX.

Re: mingw win64 comatibility

Ralf?
This is the last task... OpenSSL, mingw64 and other projects already
accepted all patches to make this environment work.
libtool is the last one.

   Hello,
  
Used git head.
Before I use cross compile, I tried to see if all tests pass on local 
 compiler.
  
My system (gentoo) has the following versions:
sys-devel/m4-1.4.11
sys-devel/autoconf-2.61-r2
sys-devel/automake-1.10.1-r1
sys-devel/libtool-1.5.26
  
Attached is the native log and win64 log (after the fix).
  
You should add *.exe to ignore... :)
  
Thanks!
  
   Alon.

   I did not know where to put this in libtool source, can you please

 It needs to be done in libltdl/config/ltmain.m4sh.

 Can you be bothered to check out the Libtool git tree or a nightly
  snapshot (see homepage for links) and, with above change, build it
  and run the testsuite on win64, please?  We'd be interested in any
  failures of
   make -k check

  (add VERBOSE=yes for verbose output of the old testsuite, and send
  tests/testsuite.log for failure of the new one).

  You'd need Autoconf for rebuilding Libtool, and also Automake for
  running all tests.

  Thanks!

 Ralf
