ata module additions now nest ata modules one deeper than any prior module. Increase heuristic used to find them by one. 2008-10-09 22:01:27 +00:00			`${.CURDIR}/../../../../.. /sys /usr/src/sys`
Fix using wrong SYSDIR after r331683. This was inadvertently overriding the first found SYSDIR with the last of /usr/src which could result in the wrong headers being used if not building from /usr/src. SYSDIR?= is not used here to avoid evaluating the exists() when unneeded.

- Missing trailing slash for a kern directory check. - Check in both places if ${_dir}/conf/kmod.mk exists. - Style fixes (lines too long). Submitted by: bde 2004-06-21 08:41:50 +00:00			`.if !defined(SYSDIR) \|\| !exists(${SYSDIR}/kern/) \|\| \`

Sigh. Use the correct path to bsd.conf.mk. It's times like this that I regret giving up coffee. 2000-05-27 01:11:17 +00:00			`.include "${SYSDIR}/conf/kmod.mk"`
