Can you confirm that this does not regress with respect to the changes
that Russell King implemented in the commit:
eedc9d83eaab2d35fb9dd1ec25b765dec964e26c
("kbuild: fix headers_exports with boolean expression")
I long time ago started a small project to do a dedicated
implementation of unifdef solely for use by the kernel.
Today we do some preprocessing in perl - and then
we pass the result to unifdef file by file.
A dedicated program could do this much faster -
and this would be a bigger incentive for the kernel supplied
tools to actually use the exported headers.
But I never got far with it and I think the code was
lost when I changed computer some time ago.
