OS X + core 2 duo + nails

[David Harvey]

Hi,

I'm getting a few "make check" failures for GMP 4.2.2 (unpatched,  
direct from GMP web site) on a core 2 duo macbook, OS X 10.4.11, when  
nails are enabled. I'm not sure if this is really a bug, since nails  
are supposed to be experimental, but nails have worked for me before  
on other platforms so I thought I should report this.

I configure with

./configure --enable-nails=1

The build appears to go fine, but then I get the following three  
failures:

ERROR
x2        = 6CC
x         = 3A
remainder = 73
FAIL: t-sqrtrem

mpz_perfect_square_p got 0, want 1
   n=0xFF45DB0B2A0D2BD2CDFC636BDB29
FAIL: t-perfsqr

mpz_set_si wrong on data[3]
FAIL: t-set_si
