of _Jv_AttachCurrentThread.
* gnu/gcj/runtime/FirstThread.java (FirstThread): Now extends Thread.

* java/lang/natClass.cc (_Jv_IsAssignableFrom): Ensure that ancestors
table index is within allowed bounds. Ensure that we dont try to access

"path.separator", and "java.io.tmpdir" from the File class, instead
of setting them explicitly.
* java/io/File.java: Do not canonicalize paths for security manager

* java/lang/natDouble.cc (parseDouble): Cannot use errno to
check for errors, since we don't want to throw exception on
overflow/underflow. Instead, trim whitespace, and then check that
_strtod_r uses up all the rest of the string.
From-SVN: r40800
* java/lang/natClass.cc (_Jv_IsAssignableFrom): Checking the
ancestors array is invalid for interfaces, so do that *after*
check that the target type is not an interface.

* gnu/gcj/runtime/FirstThread.java (main): replace / with . in jarMainClassName

for the string.
