Compatibility with ntl-8.*

[tom111]

Hi,

ntl-8.* releases are appearing and Singular is currently not compatible. Something in the conversion interface changed:

NTLconvert.cc: In function ‘CanonicalForm convertZZ2CF(const NTL::ZZ&)’:
NTLconvert.cc:504:33: error: invalid cast from type ‘const NTL::WrappedPtr<void, NTL::ZZ::Deleter>’ to type ‘long int*’
 long sizeofrep= ((long *) a.rep) [1];
                             ^
NTLconvert.cc:522:79: error: invalid cast from type ‘const NTL::WrappedPtr<void, NTL::ZZ::Deleter>’ to type ‘long int*’
 int cc= mpn_get_str (cf_stringtemp, 16, (mp_limb_t *) (((long *) (a.rep)) + 2), sizeofrep);

Hi,

i thought that i have fixed this issue with de68844
91ecc7e106...

Could you please try building Singular with NTL 8 using the current
spielwiese HEAD checkout?

Oh, I was testing the release version and did not check current HEAD. The patch works and is shipped in Gentoo's Singular package now. Thanks!
