Try again...

matusita> Ah, that's right.  Sorry.

However, if you try "make -j4 buildkernel" (4 is for example; 8 or 16
is better for modern PC), "make depend" phase will run as the same
option.

As a result, "make -j4 depend" will run during "make -j4 buildkernel"
but it's not supported as kris said.

If "make -jX buildkernel" (where X>1) is supported (I don't know it is
supported or not), following patch requires to fix this.

Anybody reconfirm this problem and check this patch does the right things?
