Log message:
Track information in a new variable BUILDLINK_ORDER that informs us
of the order in which buildlink3.mk files are (recursively) included
by a package Makefile.

Log message:
Over 1200 files touched but no revisions bumped :)

RECOMMENDED is removed. It becomes ABI_DEPENDS.

BUILDLINK_RECOMMENDED.foo becomes BUILDLINK_ABI_DEPENDS.foo.

BUILDLINK_DEPENDS.foo becomes BUILDLINK_API_DEPENDS.foo.

BUILDLINK_DEPENDS does not change.

IGNORE_RECOMMENDED (which defaulted to "no") becomes USE_ABI_DEPENDS
which defaults to "yes".

Added to obsolete.mk checking for IGNORE_RECOMMENDED.

I did not manually go through and fix any aesthetic tab/spacing issues.

I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.

I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.

As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.

As discussed on tech-pkg.

I will commit to revbump, pkglint, pkg_install, createbuildlink separately.

Note that if you use wip, it will fail!  I will commit to pkgsrc-wip
later (within day).

Log message:
Avoid extra stat() calls by not repeatedly checking whether a file
exists on the disk -- we can just check whether a variable defined by
find-files.mk is "__nonexistent__" or not.

Log message:
If the builtin expat is in /usr, not X11BASE, don't depend on X11 build
infrastructure.

Log message:
Make it possible to use a builtin expat rooted at /usr (common to some
Linux distros).  Still preferred to be pkgsrc by default in pkgsrc/mk, but
allows PREFER.expat=native to work on such systems now.

Log message:
Recursive revision bump / recommended bump for gettext ABI change.

Log message:
Bump BUILDLINK_RECOMMENDED of textproc/expat to 2.0.0 because
of the shlib major bump.
PKGREVISION++ for the dependencies.

Log message:
Update to 2.0.0:

Release 2.0.0 Wed Jan 11 2006
        - We no longer use the "check" library for C unit testing; we
          always use the (partial) internal implementation of the API.
        - Report XML_NS setting via XML_GetFeatureList().
        - Fixed headers for use from C++.
        - XML_GetCurrentLineNumber() and  XML_GetCurrentColumnNumber()
          now return unsigned integers.
        - Added XML_LARGE_SIZE switch to enable 64-bit integers for
          byte indexes and line/column numbers.
        - Updated to use libtool 1.5.22 (the most recent).
        - Added support for AmigaOS.
        - Some mostly minor bug fixes. SF issues include: 1006708,
          1021776, 1023646, 1114960, 1156398, 1221160, 1271642.

Log message:
Coalesce the common makefile code in the builtin.mk file that inspect
the X11 distribution using imake into mk/buildlink3/imake-check.mk.
imake-check.mk calls out to a helper shell script mk/buildlink3/imake-check
that generates the required Imakefiles and runs imake.  Remove the
now extraneous builtin-imake.mk files as the builtin.mk files can now
contain the name of the imake symbol to check.

Log message:
Only check for the existence of the first word of ${IMAKE} since it may
contain a command plus arguments.  We use the standard idiom to extract
the first word of a list stored in a make variable:

	VAR_CMD=	${VAR:C/^/_asdf_/1:M_asdf_*:S/^_asdf_//}

XXX This can be replaced with a more succinct use of variable modifiers
XXX when we update the bootstrap bmake to match the latest NetBSD make
XXX sources, i.e.:
XXX
XXX	VAR_CMD=	${VAR:[1]}
