[omniORB] Invalid symbol

[Sai-Lai Lo]

Erik,

We used to have omnithread running on the MIT threads package (in the
pre-linuxthread days). There is some support for it as you can see from the
code and the CPP defines in i586_linux_2.0.mk.

I think MIT thread package is almost Draft level 8 but not completely.
That would explain the absence of PTHREAD_CREATE_DETACHED.

In the final standard and all draft versions except draft 8, the default
behaviour of pthread_create is to create a thread in non-detached state.
In draft 8, the behaviour is reversed unless the detach state attribute is
set otherwise. Hence the reason for that call in the posix.cc.

So to answer your question, please look up MIT thread package to see what
is their default thread create behaviour. I think it is not the draft 8
behaviour.
