Summary: [4.6 Regression] libquadmath build broken with
pre-2.10 glibc
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: bootstrap

Bootstrap on x86_64-unknown-linux-gnu with glibc 2.7 (Ubuntu 8.04 LTS) fails

It appears that this member was new in glibc 2.10, and so configure checks or
version checks are needed to avoid requiring it when building with older glibc.
