Re: Octave-3.3.54-source build on Cygwin

3.4.4-999 is not recommended.
use 4.4.3-3 instead.

According to the recent READ.cygwin,

******************************
The latest development Octave development sources (octave-3.3.54+)
are built 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 

"--enable-float-truncate" is needed for the following bug:
http://thread.gmane.org/gmane.comp.gnu.octave.bugs/12361/focus=12404
Without it, one of the quadgk test will fail as
"a=a" could be false due to truncation problems with 
complex numbers. 
******************************
