Subject: Bug in Ruby 1.8.2 'mkmf.rb' ?

Hi all!

	I have a file called 'extconf.rb' that used to run fine
under Ruby 1.8.0, but now seems to have problems in Ruby 1.8.2 Windows XP Pro SP2
(2005-12-25 [i386-mswin32] - from the single .EXE installer).
First off, here is the extconf.rb file:

--------------------------------------------------------------
require 'mkmf'
create_makefile('RubyBarChart')

# Add on to end of Makefile...
open('Makefile', 'ab') {|mf|
   mf.puts <<EOM

RubyBarChart_wrap.cxx: RubyBarChart.i Makefile extconf.rb Account.h Contract.h Portfolio.h Tick.h EntryExitSystem.h Order.h PositionSizing.h
\tswig -c++ -ruby $(CPPFLAGS) -DDEFI_CPP_ANSI RubyBarChart.i

Tick.obj: Tick.cpp Tick.h

Account.obj: Account.cpp Account.h PositionSizing.h Order.h Contract.h Tick.h

PositionSizing.obj: PositionSizing.cpp PositionSizing.h Order.h Contract.h Tick.h Account.h

EntryExitSystem.obj: EntryExitSystem.cpp EntryExitSystem.h Tick.h

Contract.obj: Contract.cpp EntryExitSystem.h Tick.h Contract.h Portfolio.h PositionSizing.h Account.h

Portfolio.obj: Portfolio.cpp Portfolio.h Contract.h

EOM
}
--------------------------------------------------------------

Now, here are the diffs between the old Makefile and the new Makefile:
7,8c7,8

< hdrdir = $(rubylibdir)/$(arch)

--------------------------------------------------------------------------

	Notice on the 'OBJS' line, how the old version caught the build
of RubyBarChart_wrap.obj, but the new one doesn't?  This appears to be
a bug.

	Any ideas?  Am I doing something wrong?  Thanks!
