Hi
It looks like the build instructions may be slightly out of
date and I am getting a build error. Help appreciated.
I will probably commit a significant update in the next couple of days.
Is it assumed that the BSP is installed along side the tools
now and not in a separate directory?

This is a strange error. Can you look at the pre-processed file to figure out
the conflicting types?
The issue is subtle to spot. The BSD code apparently cpp's timezone
into _timezone.
$ grep settimeofday /tmp/*.i
int settimeofday (const struct timeval *, const struct timezone *);
int settimeofday(const struct timeval *, const struct _timezone *);
You are in the middle of this code right now so I hope you have a better
eye for spotting the root cause.
