not return ENOEXEC. This is because image activators should return -1 if they
don't claim an image. They should return ENOEXEC if they do claim it,
but cannot load it due to sime problem with the image. This bug was
preventing static compilation of the osf/1 module. I'm surprised it
did not cause more problems.

History:
The bulk of this code was obtained from NetBSD approximately one year
ago (I have taken care to preserve the original NetBSD copyrights and
I thank the authors for their work.) At that time, the OSF/1 code was
what was left over from their initial bootstrapping off of OSF/1 and
did not provide support for executing shared binaries.
I have independently added support for shared libraries, and support
for some of the more obscure system calls. This code has been
available for testing and comment since January of 1999 and running on
production machines here at Duke since April.
Known working applications include:
- Netscape (all versions I've tried)
- Mathematica 3.0.2
- Splus 3.4
- ArcInfo 7.1
- Matlab (version unknown)
- SimOS
- Atom instrumented binaries (built on a real OSF/1 system)
Applications which are known not to work:
- All applications linking to libmach
- Adobe Acrobat (uses libmach)
This has been tested with applications running against shared
libraries from OSF/1 (aka Tru64) 4.0D and 4.0F.
