[Lapack] Lapack for higher precision

Dear Chen,
the current work for higher precision is available since LAPACK 3.2.0.
Here is the release notes:
The XBLAS project is here:
As you will see generalized diagonalization has not been implemented and it is 
not planned anytime soon.

Another way to do is just to use the ability of the Intel Compiler that can 
work with quads (REAL*16)
This would require to modify all the LAPACK routines you need by hand, 
replacing double precision by real*16.
This would work.

Dear Lapack developer,

Hello! I am using the Lapack right now. It is very helpful for my
research. I appreciate it!

Right now, I am doing some project requiring accurater linear algebra
tools: generalized diagonalization. I want to do that for quadruple
precision. So I am wondering, how I could use Lapack for higher precision?

Thank you very much for your kindness and help!

Best wishes,
