Re: Tips for porting to new platform

Hi,

I assume the platform you are porting to is uses an x86 processor?
Then porting the runtime should be all that is required.  John Reppy
is the runtime expert (he's in Cambridge, England for the Fall), and
he should be able to tell you what the critical libraries are -- you  
probably
won't need all the functionality of the runtime libraries, and may need
to add a OS-interface library for your platform.

Regards,

Dave MacQueen
