[julia-users] Environment variables on Windows

[Rob J. Goedman]

Hi,

In Stan.jl and Jags.jl I look for environment variables.

On unix

```
ccall( (:getenv, "libc"), Ptr{Uint8}, (Ptr{Uint8},), bytestring(var))
```
works fine.

But not on Windows. I've seen

ENV("STAN_HOME")

mentioned (on http://rosettacode.org/wiki/Environment_variables#Julia , can't 
try that myself). Is that indeed how to get hold of environment variables?

Thanks,
