Please test pari-2.9.1 prerelease 1

Dear PARI developers,

We have made available a prerelease of PARI 2.9.1 (stable).

Please test the prerelease tarball:

The digital signature is 

The expected release date is set to the 1/12/2016.

This release should fix support for writebin on Windows.
This release also fix a problem when handling very large input
in algorithms based on the Chinese remainder theorem.

Please test the 64bit windows installer:

I have also built the 32bit Windows installer:

and the following standalone Windows binaries:

Done for version 2.9.1 (released 1/12/2016):
[last column crossreferences current development release 2.10.0]
      1- subst(1+x^3+O(x^6),x,x+O(x^4)) -> SEGV [#1865]                   [F1]
BA    2- lfunartin was using too much stack                               [F2]
BA    3- fflog in char 3 or 5 was slower than intended                    [F3]
      4- RgX_blocks only worked for t_INT or t_POL coeffs                 [F4]
      5- spurious bnrdlisclist entries (with negative number of real
         places...) when modulus not a conductor                          [F5]
BA    6- modular algorithms could fail for very large input               [F6]
BA    7- [mingw] writebin did not work                                    [F7]
BA    8- forprime(N=2^100,oo,...) did not work                            [F8]
