Bug ID: 60892
Summary: GCC fails to build with Linux 2.6.21 headers.
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: sanitizer
Assignee: unassigned at gcc dot gnu.org
Reporter: toojays at toojays dot net
CC: dodji at gcc dot gnu.org, dvyukov at gcc dot gnu.org,

I got the following errors while trying to build gcc-4.9 (from the 20140416
snapshot) for a Linux 2.6.21 system (Maemo 4 / diablo). Configuration was run
via
../gcc-4.9-20140416/configure --program-suffix=-4.9 --disable-shared
--enable-languages=c,c++ --enable-checking=release
I got not complaints from the, but the build failed at:

http://gcc.gnu.org/install/specific.html does not mention a minimum kernel
version for GCC.
http://gcc.gnu.org/install/configure.html does not explain how to disable
building the sanitizer.
I don't particularly mind if I can't have the sanitizer, but expect the GCC
configure script to detect that, and disable the sanitizer build automatically.
This bug is similar in spirit to bug 59068, but I'm filing a separate issue
since the root cause is different.
