Experimental Physics and
Industrial Control System

I built and used EPICS base and many of the extensions on Alphas
(DECUnix/Tru64). There were a few issues with older extensions that were
coded assuming pointer=int=long, mostly easily fixed.

The ChannelArchiver uses ftell(), feek() et al. which
are usually defined with 'long' parameters.
In addition, it actually assumes those 'long' values
to be 32bit offsets.
In case your 64bit compiler uses sizeof(long) != 4,
it'll break.
I assume it would be fairly easy to make it
run on 64bit systems, but it would still
have the same file size limits as on 32bit systems
unless the file format is changed to also use 64bit
pointers.
