Bug #1368: ruby19 trunk (svn revision 23160) build fails compiling dl ext on win32

Hi,

In attempting to build from the current svn trunk (revision 23160)
on win32, I'm getting a failure linking the dl extension.

(Building on WinXP, Visual Studio 2003, cl.exe version 13.10.6030)

I configured as follows:

win32\configure.bat --prefix=m:/dev/ruby-build/trunk --program-suffix=19
nmake

The error was:

compiling dl
  cl -nologo -LD -Fe../../.ext/i386-mswin32_71/dl.so callback-0.obj callback-1.obj
callback-2.obj callback-3.obj callback-4.obj callback-5.obj callback-6.obj
callback-7.obj callback-8.obj cfunc.obj cptr.obj dl.obj handle.obj

-pdb:dl-i386-mswin32_71.pdb -def:dl-i386-mswin32_71.def
LINK : fatal error LNK1181: cannot open input file 'callback-0.obj'


I experimented by entering the ext/dl/callback directory and manually
running mkcallback.rb and extconf.rb and moving the resulting 
callback-*.obj to the ext/dl directory... But then I get different
link errors:

   Creating library dl-i386-mswin32_71.lib and object dl-i386-mswin32_71.exp
callback-8.obj : error LNK2001: unresolved external symbol _rb_DLStdcallCallbackAddrs

callback-0.obj : error LNK2001: unresolved external symbol _rb_DLStdcallCallbackAddrs
callback-1.obj : error LNK2001: unresolved external symbol _rb_DLStdcallCallbackAddrs
callback-2.obj : error LNK2001: unresolved external symbol _rb_DLStdcallCallbackAddrs
callback-3.obj : error LNK2001: unresolved external symbol _rb_DLStdcallCallbackAddrs

etc.

So I'm a little lost at this point.

Hope this helps,

Bill
