How did you initialize _local_ for a DLL _impure_ptr? Main program knows 
nothing about it! The only way I see is to place reent_data structure to 
cygwin.dll and modify fork() code to create a copy of it in a child 
process...

Place var_name to a .def file, build a dll and import library. Now You can 
access this global data - variable __imp_var_name contains the pointer to 
var_name.
