Paul,

That is pretty funky.  I tried building on Linux and get this:

warmerda at gdal[122]% make
/bin/sh ../../libtool --mode=compile g++ -Wall  -g -DDEBUG  -I../../port -I../.
/gcore -I../../ogr  -c -o gxfdataset.o gxfdataset.cpp
  g++ -Wall -g -DDEBUG -I../../port -I../../gcore -I../../ogr -c gxfdataset.cpp
-fPIC -DPIC -o .libs/gxfdataset.o
  g++ -Wall -g -DDEBUG -I../../port -I../../gcore -I../../ogr -c gxfdataset.cpp
o gxfdataset.o >/dev/null 2>&1
/bin/sh ../../libtool --mode=compile gcc -Wall  -g -DDEBUG   -I../../port -I../
./gcore -I../../ogr  -c -o gxfopen.o gxfopen.c
  gcc -Wall -g -DDEBUG -I../../port -I../../gcore -I../../ogr -c gxfopen.c  -fPI
  -DPIC -o .libs/gxfopen.o

In short, the makefile seems to know to use the configured C++ compiler for
gxfdataset.cpp and the configured C compiler for the remaining .c files.   What
are the CXX and CC macros set to in your GDALmake.opt?  I am assuming that since
you got as far as GXF that the C++ compiler must be setup properly though if
not you could definately see this behaviour.  If that is the case you could
either hand edit your GDALmake.opt or rerun configure with "CXX=CC" in
your environment or something similar.

Best regards,
