 A new binary parser allows projects using a _MinGW GCC_ toolchain to make use of core CDT GNU tool support in the same manner as projects using a _Linux GCC_ toolchain.
 For example, users may now invoke GNU `objdump` by double-clicking on a Windows PE64 executable file.

+## Cross GCC toolchain uses GNU Elf Parser

+Enhancements to core CDT GNU tool support accommodate projects using a _Cross GCC_ toolchain in the same manner as projects using a _Linux GCC_ toolchain.
+For example, users may now invoke a build of GNU `objdump` provided by the configured toolchain by double-clicking on an ELF executable file.
+The correct GNU tool prefix (eg `arm-none-eabi-`) is provided by a CDT _Build Variable_ named `gnu_tool_prefix` when a project is configured to use the _GNU Elf Parser_.
+New projects using a _Cross GCC_ toolchain are now configured to use this binary parser by default.
