            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.

Too old Linux kernel at this point, over 14 years old.
