[Fortress-interest] trouble reading preparsed library AST (cygwin install worked... sort of)

[Eric Lavigne]

Dear Sukyoung,

Your revision 75 fixes the problem. The following transcript shows how
Fortress works on Cygwin after your fix. There is no longer an error
message, and the interpreter can run more than three times faster by
using the JST file from a previous run.

Thank you,
Eric

$ ./fortress hello.fss
Parsing hello.fss with the Rats! parser: 235 milliseconds
Missing or stale preparsed AST, rebuilding from source
Parsed C:\cygwin\home\Eric\fortress\ProjectFortress\FortressLibrary.fss:

Hello, World!
finish runProgram

Eric@anakin ~/fortress/ProjectFortress
$ ./fortress hello.fss
Parsing hello.fss with the Rats! parser: 204 milliseconds
Read C:\cygwin\home\Eric\fortress\ProjectFortress\FortressLibrary.jst:
266 milliseconds
Hello, World!
finish runProgram
562 milliseconds
