Does vxWorks 5.5.1 support dual-core processors, I thought the first vxWorks
release that can make use of SMP is vxWorks 6.7 or 6.8? I do know that the
EPICS operating-system-dependent interface software for vxWorks was not
designed for or tested on SMP systems, so I think that the only way this
combination might work would be if the second core was turned off or only used
for non-EPICS code.

I have recently been helping another user to cross-compile EPICS for vxWorks
on a Windows system. He is using the cygwin-x86 target architecture for the
host build rather than win32-x86 or win32-x86-mingw and has had several
problems with that combination (related to Cygwin's /cygdrive/... paths), but
he has finally managed to get this to work. As a result I would recommend
that you choose win32-x86 or win32-x86-mingw for your host architecture, but I
don't foresee any major problems with using Windows like that.
I would recommend that you upgrade your Base version though, 3.14.8.2 came out
almost 5 years ago in January 2006. There is no technical reason to stick
with the same version across all your IOCs, and there could be issues that we
have fixed since then which might make building the older version hard or even
impossible on newer compilers.
