according to trail this has been fixed in 3.2.3, 3.3, and 3.4, closing then as fixed.

Actually, while this is fixed on 3.2.3 and 3.3, I hit the same problem
again building 3.4:

I looked briefly at the Makefile and it wasn't obvious how "-lpthread"
was getting added under hpux 10.20.

According to the submitter it is broken for 3.4, but was fixed for 3.2.3 and 3.4.

[Daniel Berlin]

Please target 3.4 regressions at milestone 3.4, so people don't have to do
summary searches to try to determine what should be fixed for 3.4
I'm not sure it's actually necessary to mark it as a 3.4 regression in the
summary, as we could use a bug flag for regression rather than dirtying
the summary.

This is about a build failure on HPUX10.20, complaining at some point that 
"-lpthread" cannot be honored.

It is coming from a Linker_Option pragma in 5hsystem.ads, which should not be
there. Was added recently to 3.4 only, during some synchronization operation.

The patch below allows the build to proceed by removing the culprit lines.
It also removes the  "ZCX_By_Default" bit, set during the same synchronization
option, and which needs other changes to be functional.

Full build successfull on HPUX11.00, ensuring that it does not break anything
there. I don't have a 10.20 machine handy at this point, but it should
definitely fix the problem at hand, and apart from a couple of simple changes,
it basically reverts the file to it's 3.3 state, where the builds have been
reported to succeed.

OK to commit ?
