Gentlemen,

I have a question regarding the following tests which failed after porting GMP 4.2 to \
390 z/OS (not Linux not ASCII and not IEEE  floating point !! so I can understand why \
"mpz_set_d wrong on 2^53+1")

The question is do you see anything really critical so I should worry about those \
failures ?

Regards,
Sergey
