Patch: Fix line-number lookup in creating a StackTraceElement

[Ranjit Mathew]

Hi,

    On Win32, in an exception stack trace the file name in a stack
trace element was not being printed properly. I could trace it to
the fact that since Win32 source file names could look like 
"G:/src/Foo.java", createStackTraceElement( ) in gnu.gcj.NameFinder
got confused while looking for the line number in an addr2line
location output like "G:/src/Foo.java:19".

The following patch proposes to remedy this by using lastIndexOf( )
instead of indexOf( ) to find the position of the colon separating
the file name from the line number.

Ranjit.

	* gnu/gcj/runtime/NameFinder.java (createStackTraceElement): Use
	lastIndexOf( ) instead of indexOf( ) to find the colon before
	the line number, because Win32 file names might contain a 
	drive letter and a colon at the start of an absolute path.
