[omniORB] Building on Alpha Linux 2.0

[Sai-Lai Lo]

Hi! I'd like to see omniORB2 runs on Alpha Linux. Unfortunately, the last
time I look (end of 98) the egcs compiler + linker on the alpha is still
not doing the job properly.

Indeed the thread safe exception handling seems to have sorted.

But now the executables died when it is running the ctor of global
variables, i.e. before it hits main().

In particular, it core dump when executing the ctor of omni_thread::init_t,
which call pthread_key_create() etc. We use omni_thread::init_t to ensure
that the omnithread library is initialised before main().  Now this works
on every other platform/compiler combination but on alpha linux this causes
problem. I guess the ctor is executed before the pthread library has been
initialised.

It looks to me this is a problem with the linker.

With some egcs releases, I managed to get the examples to run but then
when you past anything like a reference to a struct in a function call, the
stack frame is screwed up.

All these problems have been reported to the egcs maintainers. I do not
know if anyone is looking into it.
