Forget about LDC :)
I used outdated version of LDC (the one installed with pkg),
which does not have struct kevent_t for 12+ at all.

And I am **not** going to install up to date version of LDC,
because I prefer to use packages supplied by
repository maintainers (usually)

FreeBSD has ldc2 (old, but it **is** in the repo)
Linux has both gdc (also old) and ldc.

It looks strange - leading D compiler is not in Linux/FreeBSD 
repos :)
