What steps will reproduce the problem?
1. Compilation on Windows

What is the expected output? What do you see instead?
Expected errors related to posix 
Observed cuda code errors

What version of the product are you using? On what operating system?
chmm 0.01
Windows 7 64 bit 
CUDA 3.2
Visual Studio 2008

I decided to port this usefull software to Windows.
I expected some problems related to unistd.h and some posix functions.
However, I also got the CUDA errors about variable length arrays:
hmm.cu(374): error: expression must have a constant value
hmm.cu(446): error: identifier "INFINITY" is undefined

I can dynamically allocate array.
But since this code was correct, maybe there is a way to make it working on 
windows.

What steps will reproduce the problem?

If there are 0s in the configuration, the output will contain lots of NaN.


What is the expected output? What do you see instead?

The problem is likely due to the logarithm representation of probability,
i.e. log(0) is NaN instead negative infinity.
