Hi,

I'm having some very odd problems building the 2014.08 toolchain respin -- in the cbuild1 i686-lucid env, building glibc fails with

[ERROR]    ../sysdeps/unix/sysv/linux/bits/sched.h:127:14: error: variably modified '__bits' at file scope

(Yes, the fix is to get rid of cbuild1 and more importantly the requirement for 32-bit builds in a prehistoric environment - it builds just fine on 64-bit present-day boxes... But I don't think we want to make that change in a respin).

The "variably modified" errors remain even after hardcoding

typedef struct {

__cpu_mask __bits[16];

} cpu_set_t;

instead of relying on __CPU_SETSIZE and __NCPUBITS, and the line where it complains about alignment not being a positive power of 2 actually hardcodes an alignment of 16.

Have you run into those before?
