Trying to build zero in JDK10 taken from the current tip (r13446) fails with the problem that the definitions for the standard types from stdint.h are missing:

This affects zero only, in this particular case it was tested with linux-zero. Trying to build linux-x86, linux-ppc64el or linux-sparc with the same code base does not show this problem.

A workaround is to add an include for stdint.h to src/share/vm/runtime/vmStructs.hpp:

diff -r 9a75c2f7bf06 src/share/vm/runtime/vmStructs.hpp

However, that's obviously not the right way to fix it. I have looked at the implementations for the other CPU types and couldn't find any obvious place where stdint.h is included.
