Reproducible builds

Hi,
i wanted to make a reproducible wine builds, so that striped files produce exactly
same checksum. To achieve that, I run make that with:

export WIDL_TIME_OVERRIDE="0"

Anyway, there are 7 files out of 2750 which _always_ pickup some random value and use that consistently. Why are these libraries built inconsitently? Is that intentional? An example is attached.

Thanks for hint.
W.
