It seems to depend on the shell.  You run mswin or mingw ruby
from cygwin bash, no?

In such case;

  $ ./ruby -v -I ext/nodedump/ -rNodeDump -e 'puts foo["1"]'                                         
  ruby 1.8.0 (2003-09-05) [i386-mswin32]
  NodeDump V0.9

  NODE_NEWLINE:  [-e:1]
    NODE_STR:  "puts foo[\"1\"]"

  -e:1: warning: useless use of a literal in void context

However, from cmd.exe;

  > ruby -v -I ext/nodedump/ -rNodeDump -e 'puts foo["1"]'
  ruby 1.8.0 (2003-09-05) [i386-mswin32]
  NodeDump V0.9

  NODE_NEWLINE:  [-e:1]
    NODE_FCALL:  to function: 6929 (puts)
      Parameters:
        NODE_ARRAY:  size = 1
          NODE_CALL:  to method: 331 ([])
          Receiver:
            NODE_VCALL:  self.foo
            Parameters:
              NODE_ARRAY:  size = 1
                NODE_STR:  "1"
