Build Insight 6.8-1 on Cygwin 1.7.5-1

I am trying to build Insight on Cygwin for target=arm-none-eabi.  I am running 
into a problem that was reported to the mailing list in January.  Compilation 
fails with:
In file included from 
../../../insight-6.8-1/tcl/win/../generic/../win/tclWinPort.h:72,

error: conflicting types for 'select'
/usr/include/sys/select.h:31: error: previous declaration of 'select' was here

The last message from that thread suggested trying CC=gcc-3.  That did not 
help.  The same error still occurs.

Any ideas?

Thanks,
Phil
