- added support for AT91SAM7A3 flash (patch from andre renaud, thanks)

- fix trunk build for mac os x (patch from Lauri Leukkunen, thanks)
- added check for host endianness, defines WORDS_BIGENDIAN on a big-endian host (e.g. mac os-x)
- fixed bug where endianness of memory accesses could be swapped on BE hosts
- added space for zero termination of ftd2xx_layout string (from Magnus Ludin, tahnks)
