I get this failure:

If I add "#include <unistd.h>" to tparam.c, it builds fine.
Thanks for the report.
I'm more interested in why configuring for your cross-compilation
environment doesn't find any of the curses libraries or headers. Do
you have them installed?
Hello Mr Ramey and thank you for your email!
In my previous build, I didn't have ncurses set as a dependency of bash, so
bash was getting built first -- and then there was no ncurses for it to find.
I made sure ncurses was already available and the initial problem went away.
When I configured ncurses (6.5) using the default settings, including wide
character support, I got a different failure:

I don't quite understand why having widec support caused a problem -- the bash
config.log shows:

configure:21494: aarch64-cbl-linux-gnu-gcc -o conftest

and

configure:21533: $? = 0
configure:21543: result: yes
configure:21565: checking which library has the termcap functions
configure:21568: result: using libncursesw
so the configure seems to find libncursesw just fine, but then still tries to
link against libncurses.
When I rebuilt ncurses with `--disable-widec`, the bash build succeeds.
Thank you again for your help!
Cheers,
Brett
