Hi Stewart
any reason to use your own suitesparse libs instead of the 
cygwin ones ?

$ cygcheck -c -d |grep Suite
libSuiteSparse-devel           3.5.0-1
SuiteSparse                    3.5.0-1

On the disti Suitesparse there is a specific complex patch

I have no particular problem to build latest octave dev versions ,
using all the packages already available on cygwin. 
As reported on the just updated README.Cygwin,
I am building with

configure --enable-shared \
          --enable-float-truncate \
          CC=gcc-4 F77=gfortran-4 CXX=g++-4 CPP=cpp-4 
          lt_cv_deplibs_check_method=pass_all \
          LDFLAGS=-no-undefined
