Subject: extconf.rb for Interbase on Windows

I am trying to get a Ruby extension working under Windows XP and have 
some questions. Specifically, I downloaded the interbase 0.07 release 
from RAA.

This package includes: extconf.rb, interbase.c and readmes.

I have ruby 1.8.2 release installed and VS .Net 2003 on my machine.

When I run "ruby extconf.rb"

it prints out:

checking for main() in gdslib.lib... no
checking for main() in gds.lib... no
checking for main() in fbclient_ms.lib... no

I have tried adding various combinations of 
--with-interbase-dir=c:\dev\firebirdql to the command line but to no avail.

The contents of extconf.rb are:
***** Start of extconf.rb *****
#!/usr/bin/env ruby
# ruby extconf.rb --with-opt-dir=e:/Firebird
require 'mkmf'

libs = %w/ gdslib gds /  # InterBase library

fbclientlib =  # Firebird library
   case RUBY_PLATFORM
   when /bccwin32/
     "fbclient_bor"
   when /mswin32/
     "fbclient_ms"
   else
     "fbclient"
   end
libs.push fbclientlib

test_func = "isc_attach_database"

# for ruby-1.8.1 mkmf
case RUBY_PLATFORM
when /win/
   libs.find {|lib| have_library(lib) } and
     have_func(test_func, ["ibase.h"])
else
   libs.find {|lib| have_library(lib, test_func) }
end and

create_makefile("interbase")
***** end of extconf.rb *****


The mkmf.log file output (for the fbclient_ms section) looks like:


***** start of mkmf.log *****

I have VS Net 2003 on my machine.

It seems I am missing a step to get it to find the interbase library and 
header Does anyone have any suggestions?
