How do you pass your unicode env? Do you set the CREATE_UNICODE_ENVIRONMENT
flag?

Is your environment big (> 32K)? Up to 1.5.25 the environment is
fetched using GetEnvironmentStringsA, which has a bug in (at least)
Windows XP which results in a truncated environment in the child. And
it's not truncated to 32K, but much less from my testing. Something
along the lines of sizeof (child_env) == sizeof (parent_env) % 32K.
Other than that, I have no idea. PATH is taken from the parent like
any other env var. Are you *sure* there's not some bug in your app?
