        Compiling MSWindows binary of Asymptote under CYGWIN-x86_64

First run build-asymptote on Linux. This will build the documentation
and source tar ball and copy them to a directory ~/shared which needs to be
shared via virtualbox to the cygwin build environment.

Install these cygwin packages:

wget
make
patch
gcc-g++
autoconf
bison
flex
w32api-headers
w32api-runtime
zlib-devel
libGLU-devel
libtirpc-devel (SRC)
libncurses-devel (SRC)
libreadline-devel (SRC)
libfftw3-devel (SRC)
libgsl-devel (SRC)
automake
libtool

ln -s /usr/include/tirpc/rpc /usr/include/rpc
ln -s /usr/include/tirpc/netconfig.h /usr/include/netconfig.h
ln -s /usr/lib/libtirpc.a /usr/lib/librpc.a

mv /usr/include/GL /usr/include/GL.orig

Build and install from /usr/local/src:

gsl-devel
./configure --prefix=/usr
make install

ncurses-devel
./configure --prefix=/usr
make install

readline-devel
./configure --prefix=/usr --without-curses --disable-shared
make install

fftw3-devel:
./configure --prefix=/usr --enable-shared 
make install

Compile static libraries from source:
tirpc-devel
./configure --prefix=/usr --disable-gssapi
make install

termcap-1.3.1
./configure --prefix=/usr
make install

git clone http://github.com/vectorgraphics/asymptote

cd /usr/include
