Log message:
Make this package build on platforms that don't define MNT_UNION.

Log message:
Don't limit extern "C" to certain Sun compiler. It is never wrong to do
that for C headers in C++ programs, but GCC does it by default for
system include directories.

Log message:
DESTDIR support.

Log message:
Fixed some pkglint warnings.

Log message:
Use statfs instead of statfs on FreeBSD. Peter Schuller's bulk build
indicates that it is needed.

Log message:
Change the format of BUILDLINK_ORDER to contain depth information as well,
and add a new helper target and script, "show-buildlink3", that outputs
a listing of the buildlink3.mk files included as well as the depth at
which they are included.

For example, "make show-buildlink3" in fonts/Xft2 displays:

	zlib
	fontconfig
	    iconv
	    zlib
	    freetype2
	    expat
	freetype2
	Xrender
	    renderproto

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:
Mention how to enable rpcbind(8); may avoid confusion.

Log message:
Removed the superfluous "quotes" and 'quotes' from variables that don't
need them, for example RESTRICTED and SUBST_MESSAGE.*.

Log message:
Aligned the last line of the buildlink3.mk files with the first line, so
that they look nicer.
