DLL creation problem

[DJ Delorie]

> 	char **envp = environ;

When you have a variable in a DLL, the dll exports the *address* of
the variable, not the variable itself.  Not a problem with functions;
they're addresses anyway.  But, with a data item, it's a little funny.
Cygwin handles this by telling gcc that the data item is imported from
a dll, and gcc automagically adds the pointer dereferencing code.
Thus, a simple assignment might turn into a dereference when compiled.
