sdcc-2.6.0-asz80-symlen.patch is unnecessary, and it and the corresponding
section from the README can be removed.
These changes have not yet been incorporated or verified.
These changes *have* been incorporated but only partially verified. In order
to get a successful compilation, I had to copy stdarg.h out of the SDCC source
(at sdcc/device/include/stdarg.h) to include/nuttx/stdarg.h.
There are also some library related issues when you get to the final build
that I have not looked into yet.
If you want to back out these change and continue to use the older toolchain
in your build, simpy define the following in your configuration file:
CONFIG_SDCC_OLD=y
