build error

[Thomas Wuerthinger]

Vasanth,

I'll provide you with exactly what you describe below. However, I'll still need another 24 hours - will let you know when it is pushed.

I guess that you'll later want to add a HSAIL implementation. Could you please advise as to what would be your requirements and constraints regarding register allocation for the HSAIL code?

It looks like the build scripts may need to be updated so that they know where to find the source file for the above newly added package.
