----
This is actually the same type of error I had building Bash when I used the latest gawk to fix bug 756136 (which I ended up reverting).

I'm a bit lost with this one, especially because I didn't hit this on a previous attempt with /usr/local/include hacks.

[Comment 1 Sam James 2020-11-23 00:24:29 UTC]

I didn't want to mess around with applying the patch because I'd have needed to autoreconf it externally and apply a patch(?)

So, I switched to app-shells/bash-5.1-rc3 and the corresponding sys-libs/readline-8.1_rc3, and added keywords there locally. Bash has now built.

[Comment 2 Fabian Groffen 2020-11-26 16:05:45 UTC]

I've unmasked bash-5.1 in the BigSur profile, using an accept_keywords entry
