Subject: [ruby-core:32469] ruby.lib vs VC++

Here's a nice sample program to illustrate my problem:

  http://github.com/time/rubyholdem.git

When I compile Ruby with Visual Studio 2005, via NMAKE, I get
msvcr80-ruby191.lib and msvcr80-ruby191-static.lib.

When my own VC++ project links to the former, I can't debug inside
Ruby. When I link to the latter I get a zillion linker errors.

So when I grab that RubyHoldem program, and switch its ruby LIB to the
msvcr80-ruby191-static.lib, I get a shorter and more concise
diagnostic:

msvcr80-ruby191-static.lib(ruby.obj) : error LNK2005: _DllMain@12
already defined in rubyholdem.obj
   Creating library C:\phlip\tools\rubyholdem\\whuser.lib and object
C:\phlip\tools\rubyholdem\\whuser.exp
LINK : warning LNK4098: defaultlib 'MSVCRT' conflicts with use of
other libs; use /NODEFAULTLIB:library
rubyholdem.obj : warning LNK4049: locally defined symbol _rb_eException imported
rubyholdem.obj : warning LNK4049: locally defined symbol
_rb_eRuntimeError imported
C:\phlip\tools\rubyholdem\\whuser.dll : fatal error LNK1169: one or
more multiply defined symbols found

Aaaand turning on /NODEFAULTLIB, like it says, leads to the same big
cascade of errors that I get.

A little help?
