NetBSD thor 1.5.3 NetBSD 1.5.3 (GENERIC) #0: Tue Aug 27 17:42:36 EST 2002     awhite@thor:/usr/src/sys/usr/src/sys/arch/i386/compile/GENERIC i386
>Description:
From /usr/share/mk/bsd.sys.mk:

.if defined(DESTDIR)
CPPFLAGS+= -nostdinc -idirafter ${DESTDIR}/usr/include
LINTFLAGS+= -d ${DESTDIR}/usr/include
.endif

Notably missing from this is the C++ include directory, /usr/include/g++.  Thus, C++ programs will break on mkdep or compile once DESTDIR is set.
>How-To-Repeat:
Compile a C++ program using the toolchain when DESTDIR is set.
>Fix:
Add -idirafter $DESTDIR/usr/include/g++ to CPPFLAGS
Add -d ${DESTDIR}/usr/include/g++ to LINTFLAGS
