     2 Starting with Raptor 2.13.0, it is also possible to use Cygwin 1.7 instead of

     3 Cygwin 1.5. Some work was necessary to add support for Cygwin 1.7 due to a

     4 change in command line interface in some of the Cygwin tools.

     5  

     6 Due to this change in the command line interface, we have had to introduce the

     7 SBS_CYGWIN17 environment variable whose value should be the root directory of

     8 the Cygwin 1.7 installation. We hope this is temporary and that we can remove

     9 this at some point. The following bullet points indicate the order of

    10 precedence of the SBS_CYGWIN and SBS_CYGWIN17 environment variables.

    11  

    12 * SBS_CYGWIN set,   SBS_CYGWIN17 unset: assume Cygwin 1.5 is being used

    13 * SBS_CYGWIN set,   SBS_CYGWIN17 set:   assume Cygwin 1.7 is being used

    14 * SBS_CYGWIN unset, SBS_CYGWIN17 set:   assume Cygwin 1.7 is being used

    15  

    16 You will get errors if you set SBS_CYGWIN to be the root of a Cygwin 1.7

    17 installation directory and if SBS_CYGWIN17 is not defined correctly.
