[Samba] Trouble building 4.2rc4 on FreeBSD

[Russell Poyner]

I'm attempting to build 4.2.0rc4 on a FreeBSD 10.0 system. There seems 
to be a problem with finding the system headers. Specifically 
lib/texpect/texpect.c seems to not be finding /usr/include/sys/signal.h

Some hints on waf or building samba would be appreciated

The errors:
