Yes it is.  This is the current breakdown:

std.c		- standard C headers
std.c.posix	- POSIX headers
std.c.posix.sys	- same
sys.windows	- Windows-specific D code
sys.windows.c	- Windows C headers

and so on for linux, darwin, etc.

Currently, the files in sys.linux.c duplicate some information in 
std.c.posix, but I am gradually phasing it out.

The current Posix headers only support Linux and (to a limited degree) 
Darwin, but it would be easy enough to add other OSes as well.  I'm 
taking care of them on an as-needed basis, but there's a decent bit of 
functionality available so far.
