The GDB 4.8 features are:
* Guile scripting support.
* Python scripting enhancements.
* New commands:
** guile
** guile-repl
** info auto-load guile-scripts [REGEXP]
* New options:
** maint ada set ignore-descriptive-types (on|off)
** maint set target-async (on|off)
** set|show auto-load guile-scripts (on|off)
** set|show auto-connect-native-target
** set|show guile print-stack (none|message|full)
** set|show mi-async (on|off)
** set|show print symbol-loading (off|brief|full)
** set|show record btrace replay-memory-access (read-only|read-write)
* Remote Protocol:
** The qXfer:btrace:read packet supports a new annex 'delta'.
* GDB/MI:
** A new option "-gdb-set mi-async" replaces "-gdb-set target-async".
* New target configurations:
** PowerPC64 GNU/Linux little-endian
* btrace enhancements:
** The btrace record target now supports the 'record goto' command.
** The btrace record target supports limited reverse execution and
replay.
* ISO C99 variable length automatic arrays support.
* It is no longer required to "set target-async on" in order to use
background execution commands (e.g., "c&", "s&", etc.).
