 you will need an assembler. This is worth doing because it will result in

 To build OpenSSL using CygWin32:

 To build OpenSSL using Cygwin:

 * Install CygWin32 (see http://sourceware.cygnus.com/cygwin)

 * Install Cygwin (see http://sourceware.cygnus.com/cygwin)

 * Install Perl and ensure it is in the path (recent Cygwin perl 

   (version 5.6.1-2 of the latter has been reported to work) or

   ActivePerl)

 * Run the CygWin bash shell

 * Run the Cygwin bash shell

 * $ tar zxvf openssl-x.x.x.tar.gz

   $ cd openssl-x.x.x

   $ ./Configure no-threads Cygwin

   $ ./Configure Cygwin

   [...]

   $ make

   [...]

 This will create a default install in /usr/local/ssl.

 "make test" and normal file operations may fail in directories

 mounted as text (i.e. mount -t c:\somewhere /home) due to CygWin

 mounted as text (i.e. mount -t c:\somewhere /home) due to Cygwin

 stripping of carriage returns. To avoid this ensure that a binary

 mount is used, e.g. mount -b c:\somewhere /home.
