Make knows how to compile C++ files as well, it recognizes .cc, .cpp,
and .C (Capital C) extensions.  Please try it.

This is redundant, Make already knows all this stuff.  If you have
specific problems, please report them.

You don't need gpp to compile, only to link.  And in a Makefile, this
isn't really a problem: you can simply add -lstdcxx to the LDLIBS
variable, like this:

LDLIBS = -lstdcxx

Alternatively, say this:

LINK.cc = gpp $(CXXFLAGS) $(CPPFLAGS) $(LDFLAGS)
LINK.cpp = gpp $(CXXFLAGS) $(CPPFLAGS) $(LDFLAGS)
