I think you are missing the facts:
o I am using a non-default compiler installation, so
that mu C++ include directory is in /usr/local/include
o DESTDIR is set
o Look in /usr/share/bsd.prog.mk for ".if defined(DESTDIR)";
it overrides my compiler defaults for the values of CFLAGS
and CXXINCLUDES. This makes them _WRONG_:
.if defined(DESTDIR)
CFLAGS+= -I${DESTDIR}/usr/include
CXXINCLUDES+= -I${DESTDIR}/usr/include/g++
.endif
o Look in /usr/share/bsd.lib.mk: it does the same thing:
.if defined(DESTDIR)
CFLAGS+= -I${DESTDIR}/usr/include
CXXINCLUDES+= -I${DESTDIR}/usr/include/g++
.endif
Specifically, you get the _WRONG_ <rtti> and other C++ header
files, which makes exceptions and run time type information
_NOT WORK_.

The /usr/include/g++ files are _WRONG_...
The /usr/local/include/g++ are _RIGHT_...
The BSD .mk files insist on using the wrong .mk files; I don't
know how much clearer I can make it?!?
