Subject: Problem with mkmf and spaces in directory names?

Hi all,

Ruby 1.8.1
Windows 2000

I installed libexpat in C:\Program Files\Expat and then tried to
install Quixml.  I made one modification to the extconf.rb file, using
'have_library("libexpat")' instead of 'have_header('expat.h')...'. 
Then I ran this:

C:\ruby\src\QUIXML~1.1>ruby extconf.rb
--with-quixml-include='c:\program files\e
xpat\source\lib' --with-quixml-lib='c:\program files\expat\libs'

But it fails.  Here's the mkmf.log output:

have_library: checking for main() in libexpat.lib...
-------------------- no

/* end */

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

However, everything works fine if I install expat in c:\expat.  So, it
looks like the space in the directory name is causing a problem.  Is
this a problem with mkmf.rb or is it a bug in the Windows linker?
