configure fails when generated with debian's autoconf 2.64-1 from unstable

[explicitcall]

when doing sh boot&&./configure on ghc-HEAD with latest patches with debian's autoconf 2.64-1 from unstable installed, I get this:

checking for ghc-pkg matching /home/user/local/bin/ghc... /home/user/local/bin/ghc-pkg
./configure: line 6156: syntax error near unexpected token `indResVersion=$fptools_cv_windres_version'
./configure: line 6156: `fi    indResVersion=$fptools_cv_windres_version;'

after that configure script stops

when I downgrade to autoconf 2.63-3 from testing, configure runs normally

generated buggy configure script is attached

See #3414, especially the two patches attached to that ticket which I think fix a couple of the issues; not all of them though.

This patch allows terminfo to configure.

It looks like those three patches (one in this ticket and two in #3414) will solve the problem - at least, they did for me.

Assigning to igloo since patches have been posted.

Thanks; I've applied the other two patches, and sent this one to Judah.

This patch has now also been applied.
