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:

git
wget
make
patch
gcc-g++
autoconf2.5
bison
flex
w32api-headers
w32api-runtime
zlib-devel
libGLU-devel
libtirpc-devel (SRC)
libreadline-devel (SRC)
libfftw3-devel (SRC)
libgsl-devel (SRC)
automake1.15
libtool

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

Build and install static libraries from /usr/local/src:

gsl-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

tirpc-devel (if rpc library is unavailable):
./configure --prefix=/usr --disable-gssapi
make install
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

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

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

cd /usr/include
patch -p0 < ~/asymptote/patches/cygwin_glu.patch

mkdir -p ~/dll/cygwin
cp /usr/bin/cygwin1.dll ~/dll/cygwin

cd
~/asymptote/build-scripts/build-freeglut

install texlive

mkdir ~/CTAN
cp -a ~/asymptote/build-scripts/README-binaries ~/CTAN
