Our V7, operational on a fairly large 11/44 (i.e. a fair number of device
drivers) as of a year ago, came out this way:

place	lines	bytes

sys	6741	126611
dev	4877	97353
h	1545	41264
conf	2178	45951
----------------------
	15341	311179

"sys" is most of the kernel, "dev" is device drivers and some related items,
"h" is include files, "conf" is configuration control and the one big lump
of assembler for low-level functions.  (The assembler stuff is in "conf"
because it is slightly pdp11-model-specific.)  This excludes device drivers
not in our operational configuration.

In general, V7 was fairly compact.  The entire distribution -- sources,
binaries, manual pages, everything -- was 11 MB.
