[ap-utils] Solaris build problems

[Daniel E. Eisenbud]

While I was at it, I tried to build on Solaris.  No <features.h>, and
I'm not sure uint_32_t is defined anywhere in /usr/lib.  I fixed that,
and then realized that I didn't have ncurses installed, so I stopped
there for now.  I'll try again later with ncurses, if I have a chance.
(Any reason it shouldn't work with regular SysV curses?)
