 The hpux 10.20 build was successful with the enclosed patch.  Possibly,
 the hpux test that you added should be after the DCE block but that

 I'm also going to remove it from THREADSLIB as I don't believe it should be
 there either.

  John, could you please give it a try on HPUX 10 (removing -lpthread from
  TGT_LIB) ?
 
  This will hopefully let you complete the build, and it appears wrong anyway.

  Thanks for the clarification, Arno.
 
  For the remaining issue at hand:
 
    >   TGT_LIB = /usr/lib/libcl.a -lpthread
 
    >  ../../xgcc [...] -o ../../gnatmake [...]  /usr/lib/libcl.a -lpthread

  it seems to me that -lpthread should not be part of TGT_LIB, which is
  only used for the tools. AFAICS, removing it would fix the problem on HPUX
  10.20, and I checked that builds are still OK on HPUX 11.00.
 
  How does it look to you ?

 Actually no, HP-UX 10.20 only has DCE threads.
 
 What we did was to build two GNAT run time (one for DCE, one for pthread),
 with the idea that: under 10.20, only the DCE run time can be used;
 under 11.00, both could be used.
 
 We now no longer build dce under 11.00, as this library caused too many
 problems (both in terms of posix compliance and reliability).

 There is the GNU pth implementation and possibly HP provided it as an
 option.  However, the standard thread implementation was DCE threads.
 
 I haven't really had a chance to work on the thread implementation
 under hpux 11.  However, I have decided that probably we should use
 a multilib implementation as HP's "weak" support doesn't conform to
 the SYSV ABI with respect to undefined weak symbols.

  I think it's OK as you did it. Additionally moving the block after the DCE
  section would have been useful if this was to work for DCE/HPUX11, but there
  is no point.

  The problem you see may be solvable independently, though, as I believe
  "-lthreadlib" is not supposed to be there for the "gnatmake" target anyway.
 
  I'll dig a bit and suggest an approach shortly.

 The build was successful and libgnat doesn't contain any references
 from the unwind library.  However, I just deleted the 5htraceb.adb
 from the DCE section.  Is it possible that the new block should follow
 the DCE block in 3.3 and the trunk?

  I don't see mention of this in the 3_2-branch version of Makefile.in.

 It doesn't fix the problem when starting from gcc-3.2.3.  We appear
 to need a similar patch for the 3.2 branch.  I am trying the obvious
 to rebuild 3.2.3 but note that in the 3.2 branch 5htraceb.adb is also
 included in the DCE case.  I'm also wondering about libcl.
