Please test pari-2.7.2 prerelease 2

[Bill Allombert <Bill.Allombert@math.u-bordeaux.fr>]

Dear PARI developers,

I have made a second prerelease of PARI 2.7.2 to address the following serious
issues

   27- FpXY_evaly() wrong when evaluating at 0                            [F56]
   28- [mingw] gp could crash at start up [#1607]                         [F57]

Windows installer:

basic windows binary:

The expected release date is still set to the 19/09/2014

Below is the changelog:

Done for version 2.7.2 (released 19/09/2014):
[last column crossreferences current development release 2.8.0]

  Fixed
    1- gaffsg(0, t_PADIC): wrong valuation                                [F21]
    2- (t_INTMOD with word-sized modulus)^(huge negative power) [#1584]   [F24]
    3- (gp -p N) or (primelimit=N in gprc_ for N >= 436273290 resulted in an
       incorrect primetable. N.B. Such commands are now useless: needed primes
       are produced dynamically anyway.                                   [F25]
    4- monomial(exact zero, d, v) returned an invalid t_POL / t_RFRAC     [F26]
    5- contfracpnqn(v, n) returned partial quotients p[-1]/q[-1] ...
       p[n-1]/q[n-1], instead of the documented p[0]/q[0] ... p[n]/q[n]   [F27]
    6- factor((3+4*I)/25) -> factor 2+I had 0 exponent [#1586]            [F29]
BA  7- iferr() could crash if some component of the t_ERROR were clones.  [F31]
    8- nffactor() could overflow the stack when default accuracy too low  [F32]
BA  9- obsolete use of E=[a1,a2,a3,a4,a6] in ellmul crashed  [#1589]      [F33]
   10- incorrect rounding in mulrr/divrr for one-word precision reals     [F34]
BA 11- multiif did not handle correctly return() in conditions [#1590]    [F35]
   12- [0..5] -> [0,0,0,0,0] on some architectures                        [F36]
   13- is_gener_Fp could return wrong results                             [F37]
   14- Fq_sqrtn(t_INT,..,&zeta) could return a wrong root of 1            [F38]
   15- bnfinit: SEGV due to precision issues [#1592]                      [F39]
   16- zm_zc_mul only worked for square zm matrices                       [F40]
   17- genus2red(0,27*x^5+97*x^4+118*x^3+60*x^2+13*x+1,3) -> bug [#1596]  [F41]
   18- [ghelp] oo loop when $COLUMNS too small [#1594]                    [F42]
   19- genus2red(x,-x^6-3*x^4-10*x^2-1,3) -> impossible inverse [#1597]   [F43]
   20- factoru(1) returned a t_MAT instead of the expected "matsmall"     [F44]
   21- FpM_charpoly wrong in small characteristic [#1602]                 [F45]
   22- when compatible = 3; series() used a random precision              [F50]
   23- genus2red(0,6*x^6+5*x^4+x^2+1,7) -> impossible inverse [#1597]     [F51]
   24- isprime() could crash on large input [#1604]                       [F52]
   25- genus2red(x^3+1,1) -> type error [#1597]                           [F53]
   26- gphelp did not handle === correctly [#1603]                        [F54]
   27- FpXY_evaly() wrong when evaluating at 0                            [F56]
   28- [mingw] gp could crash at start up [#1607]                         [F57]

Thanks in advance for testing,
Bill.
