* Changes for a clean compilation under the ZDS-II toolchain.
Minor features:
* Add logic to extract printf strings from FLASH (but there are still printf
issues for that target)
* Added a configuration for the Sure Electronics PIC32MX board. However,
higher priority tasks have stopped work on that configuration.
* Added several new configurations for the STMicro STM3210E-EVAL board.
* Added support for the STM3210E-EVAL board: (1) LCD in either landscape or
portrait mode, and (2) interrupting buttons.
* Added a configuration option to use different serial ports for debug
and for the NSH serial console (there are some issues with CR-LF
expansion and character echo if NSH is not run on the console).
* Standardized the button press and button interrupt interfaces so that they
are common across all boards.
* Added a new graphics example that focuses on placing text on the background
while pop-up windows occur. Text should continue to update normally with
or without the popup windows present.
* Added ARM stack checking logic.
See the ChangeLog for a detailed description of these changes.

nuttx-6.7
^^^^^^^^^
The 74th release of NuttX, Version 6.7, was made on August 2, 2011 and is
available for download from the SourceForge website. Note that release
consists of two tarballs: nuttx-6.7.tar.gz and apps-6.7.tar.gz. Both
may be needed (see the top-level nuttx/README.txt file for build
information). Changes in this release are summarized below:
* New OS APIs: Add the standard sem_timedwait() interface.
* FAT File System: Adds (optional) support for VFAT long file names.
* USB: Now the mass storage device can be connected when needed and
disconnected when not needed (or re-connected as a different kind of
device).
* Touchscreen Support: Defined a new NuttX touchscreen interface.
Added a driver for the TI TSC2007 touchscreen controller chip.
* NX Fonts: Add support for multiple fonts; developed a tool to
convert open source fonts into NuttX format; Converted and installed
nine new, high quality fontsets.
* NX Graphics: Add new NX APIs to support drawing of wide lines in any
orientation. Added new low level routines to set individual pixel
more efficiently.
* Build system: Added a export target that will bundle up all of the
NuttX libraries, header files, and the startup object into an export-
able tarball.
* LPC17xx: A CAN driver was contributed by Li Zhuoyi (Lzyy).
* STM32: New NX-related configurations to excercise text and graphic image
displays.
* C Library: Added a fixed precision atan2() math function.
* Bugfixes: Serial RX overrun error, FAT upper/lower NT 8.3 name
handling fixed. FAT directory allocation and initialization bug.
STM32 SDIO DMA race condition bug. eZ80 UART1 serial driver errors
