Sure.  I'm not yet familiar with the build system in place for 
distinguishing between platforms.  I see that there is a separate 
directory for Windows and a WIN32NATIVE symbol defined, so I'll figure 
out how to use these for the Cygwin version.

I haven't used the Linux drivers for FTDI yet, I don't know how similar 
they are to the Windows ones.  If they correspond one for one then it 
should be easy.

Also, I'm not particularly knowledgeable about autoconf/automake.  For 
the Win32 version, one must link in FTD2XX.lib.  I did this with a line:

avrdude_LDADD = FTD2XX.lib

in the Makefile.am file.  But this needs to put the .lib file in the 
current directory.  I'd like instead to grab the copy in the installed 
FTDI driver directory.

Under Linux I'm sure there will be a similar .so or .a to link to. 
Again, I don't know how to conditionalize things in Makefile.am to do 
the right thing when the build is on Linux vs. Windows.

Since my AVR project will ultimately be Windows based I've set up using 
Cygwin for now.  In a few days I may take a crack at Linux.

I leave on a business trip tonight until Thursday, so I probably won't 
get to post the patch until then.
