* Add support for H8/300 toolchain
|

* Add support for GCC 4.2.4 and binutils 2.19
|

* Various fixes for newer Linux environments
|
||||
* New ARM configuration using GCC 4.2.4 and binutils 2.19
|
||||
(Note: this doesn't work with NuttX yet... to nuttx TODO.txt list).
|
||||
* Add Renesas R8C/M16C/M32C configuration using GCC 4.2.4 and binutils 2.19
|
||||
* Replaced config/arm-defconfig-4.2.4 with config/arm920t-defconfig-4.2.4
|
||||
and config/arm926t-defconfig-4.2.4 because of differences in the
|

way that soft floating point is handled between these two
|
||||
architectures.
|

* Add support for gcc-4.3.3 and the ARM Cortex-M3 processor (thumb2)
|

* Add support for a blackfin toolchain using GCC 4.2.4 and binutils 2.19
|
||||
* GCC 4.2.4 no longer attempts to build libstdc++. Now we can build g++!
|
||||
* The ARM GCC-4.2.4 configuration was changed so that it now builds g++.
|
||||
* Removed building of initial and final GCC. that is not necessary because
|
||||
we do not build a libc. Now it builds almost twice as fast.
|
||||
* Removed logic to build the target GCC. That is never used.
