* gcj/javaprims.h (_Jv_uintptr_t): New typedef similar to uintptr_t in

	C99.
	* include/java-stack.h: Include stdlib.h.
	(_Jv_AddrInfo): New structure to hold address information.
	* include/posix.h (_Jv_platform_dladdr): Declare.
	* include/win32.h (_Jv_platform_dladdr): Declare.
	(backtrace): Remove declaration.
	* posix.cc: Include dlfcn.h if available.  Include java-stack.h.
	(_Jv_platform_dladdr): Define.
	* win32.cc: Include string.h.  Include java-stack.h.
	(backtrace): Remove.
	(_Jv_platform_dladdr): Define.
	* sysdep/i386/backtrace.h (fallback_backtrace): Check that a potential
	frame pointer value is 32-bit word-aligned.  Use operand of the CALL
	instruction calling the current function to find its starting address.
	* stacktrace.cc: Do not include dlfcn.h.  Include platform.h.
	(_Jv_StackTrace::getLineNumberForFrame): Use _Jv_platform_dladdr()
	instead of dladdr().
	(_Jv_StackTrace::GetStackTraceElements): Use nCodeMap even for Windows.
	(_Jv_StackTrace::GetClassContext): Use fallback_backtrace() for
	targets with SJLJ exceptions instead of using _Unwind_Backtrace().
	(_Jv_StackTrace::GetFirstNonSystemClassLoader): Likewise.
