I have noticed that a particular section of the tree has not been building properly for a while now. Under src/add-ons/kernel/network/core, a number of files seem to be having issues. I looked at core.c, and the problems seem to be mostly missing function declarations. At first, I thought that the developers working on that bit had just missed adding the declarations, but then I noticed that 2 of the missing functions and a missing variable were declared in "sys/domain.h". "sys/domain.h" is included by core.c, but the declarations only appear if _KERNEL_MODE is defined. This would appear to be more of a problem with the build system. Can somebody more knowledgeable on these topics take a closer look and fix the problem? I think there are other network related things that are having build issues also, but I did not investigate them. Gabe
