I was able to compile bash3.2 under haiku, and if compiled without support for multibyte characters (which is currently broken in haiku), it even works correctly. I haven't tried to crosscompile it yet from within the build system, although when I tried long ago, I ended up with a non working bash. I think we should ship the alpha version with the current bash, though, since this change could bring some new issues not immediately visible. What do you think ?
