[openssl-dev] Assembler warns about constants in poly1306-x86_64.pl

I can't reproduce this. I generated file with 'perl
crypto/poly1305/asm/poly1305-x86_64.pl nasm a.asm', and then compiled it
with 'yasm -f win64 a.asm', no warnings observed. 'yasm --version' does
print 1.3.0. How do corresponding lines read in *your* *generated* file.
Mine are 'and     r[89],-2147483648'
