• configure.ac: Pass CFLAGS to cpukit configure.
• aclocal/rtems-flags.m4: Remove (Unused).
• aclocal/prog-ccas.m4: Remove $(GCCSPECS).
• aclocal/env-rtemsbsp.m4: Comment out CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V, CPU_CFLAGS.
• aclocal/prog-cc.m4: Don't invoke _RTEMS_FLAGS to set up RTEMS_CFLAGS.
• automake/compile.am: AM_CFLAGS = RTEMS_CFLAGS. Add AM_CXXFLAGS. Remove CPPFLAGS, CFLAGS, CPU_CFLAGS, CFLAGS_OPTIMIZE, ASFLAGS. Cleanup comments.

 ##
 
-## -------------------------------------------------------------------------
-## NOTE: This file is rather immature and has to be considered to be 
-## almost experimental.
-##
-## Expect frequent changes -- It deserves to be cleaned up :(
-## -------------------------------------------------------------------------
-
-## The section below is based on make/compilers/gcc-target-default.cfg
-## used in former versions of RTEMS.
-
-## 
-## Set up the flags for the toolchains:
-##
-## We are considering 3 different building schemes here:
-## * Using gcc's being able to accept -specs (aka gcc-2.8 building scheme)
-## * Using gcc's not being able to accept -specs (aka gcc-2.7.2 building
-##   scheme)
-## * Using third party toolchains (aka non-gcc building scheme)
-##
-## Automake conditionals in use:
 ## RTEMS_USE_GCC     .. if we are using GCC
-
-## NOTES: 
-## * The gcc-2.8 building scheme is the nominal building scheme and
-##   is actively supported.
-## * The non-gcc building scheme requires manually setting up environment 
-##   variables and is hardly tested at all
-
-## CFLAGS_OPTIMIZE_V, CFLAGS_DEBUG_V are the values we
-## would want the corresponding macros to be set to.
-##
-## CFLAGS_OPTIMIZE, CFLAGS_DEBUG are set by the 
-## 'VARIANT=<OPTIMIZE|DEBUG>' targets to their _V values.
