Summary: Undefined symbol when building Perl Modu

Initial Comment:
I am attempting to build the Perl modules for 4.2.4 
under Win2000.  After playing with the Makefile, 
changing paths and such, SNMP.c complies, but upon 
attempting to link, I get:

"unresolved symbol _tree_head"

I see tree_head in parse.c.  The library, libsnmp.lib, 
built Ok using Visual Studio.

Other changes:

1.  used GNU regex.h
2.  commented-out "#include system.h" in SNMP.xs.  The 
compiler claimed that both direct and _dir_struc were 
multiply defined.  SNMP.c will not compile with 
system.h.
3.  commented-out "#include <unistd.h>"

I see that _tree_head is referred to in libsnmp.lib.  
Could this be a compiler issue when the library was 
created?

I changed  the following line (line 809 of SNMP.xs) : 
   extern struct tree *tree_head;
in 
   DLL_IMPORT struct tree *tree_head;
this fixes the compiler error. 
(The problem is that the tree_head is one of the 
three DATA symbols defined in libnsmp.def (visible data 
symbols in dll). the MIB symbol has the DLL_IMPORT 
declaration so it refers to a symbol in a DLL.
