Vicente, All,

On 2014-12-08 15:41 +0000, Vicente Olivert Riera spake thusly:
> - pinentry-qt4 needs Qt with accessibility support, so remove the

I was working on those build failures that happen since pinentry was
bumped to 0.9.0.

I was about to send my patches when I decided to look at the mailing
list, and found this mail of yours.

Well, I'm OK with the changes, since I've done the same.

However, this patch is doing many different things:
  - fixes the incorrect include paths;
  - fixes the build without Qt accessibility;
  - does not disable accessibility in Qt;
  - removes superfluous configure options

This should be two separate patches.

I'll shortly send what I have, and you can take them and respin if you
think I forgot something.

For one, I have included your no-accessibility patch that was since
accepted upstream, so I'll use that instead of forcefully enabling
accessibility in Qt. And as you previously discussed with Thomas P.,
this should probably be an option in Qt; accessib8ility should not
always be enabled.

Regards,
Yann E. MORIN.
