The same problem does not happen when running vfpdouble-40abcb.sh - instead, I get /mnt/disk/linaro-builds/manta-4.2.2/kernel/samsung/manta/arch/arm/vfp/vfp.h:124:3: error: implicit declaration of function 'do_div' is invalid in C99 [-Werror,-Wimplicit-function-declaration] do_div(z, mh); ^

Apparently the header defininig the do_div macro is being kicked out by the preprocessor?

The pre-processed source compiles today.

If I move stuff around in the code a little, making sure the header defining do_div is included before the first header trying to invoke it, the problem becomes reproducible with the generated /tmp/vfpdouble* files.
