On an i386, using csh:

# make build
Build started at: Mon May  3 11:58:13 BST 1999
(cd /usr/src/etc && make DESTDIR=/ distrib-dirs)
install -d -o root -g wheel -m 755 /
mtree -def mtree/NetBSD.dist -p // -u
cd /; rm -f sys; ln -s usr/src/sys sys
(cd /usr/src/share/mk && make install)
(cd /usr/src/share/tmac && make && make install)
/usr/share/tmac/tmac.an -> /usr/share/tmac/tmac.andoc
make includes
make: don't know how to make includes. Stop
*** Error code 2

However, on an arm32 using csh, this works. On the i386, doing under csh
make -n build > foo
sh foo
works. I don't see what can be platform dependent about this! Both trees
supped this morning, both running recent -currents.

Cheers,
