Subject: Compile s_llround.c with -Wno-error for x32 build
X-Git-Tag: glibc-2.21~197
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=9cd4d4abdca1329cde5ee3dcc963b8533678551e;p=thirdparty%2Fglibc.git

Compile s_llround.c with -Wno-error for x32 build

Since x32 returns 32-bit long int and 64-bit long long int in the
same 64-bit register, we make the 32b-bit lround an alias of the
64-bit llround.  Add -Wno-error for x32 build to silence the compiler.
