How is /usr/include/stdio.h being included before libgnu/stdio.h?  I 
would expect the directories specified by -I on the command line to all 
be searched before standard header file directories like /usr/include.

Could you send the output of running

touch empty-file.cc
/opt/local/bin/g++-mp-4.7 -DHAVE_CONFIG_H -v -E -I. -I.. 
-I/opt/local/include -I/opt/local/include/QtGui -I/opt/local/include 
-I/opt/local/include/QtNetwork -I/opt/local/include 
-I/opt/local/include/QtCore -I./qterminal/libqterminal -Isrc -I./src 
-I./src/m-editor -I./src/qtinfo -I../liboctave/cruft/misc 
-I../liboctave/array -I../liboctave/numeric -I../liboctave/numeric 
-I../liboctave/operators -I../liboctave/operators -I../liboctave/system 
-I../liboctave/util -I../libinterp -I../libinterp 
-I../libinterp/parse-tree -I../libinterp/parse-tree 
-I../libinterp/corefcn -I../libinterp/corefcn 
-I../libinterp/octave-value -I../libgnu empty-file.cc

on your system?

Is /opt/local/include a link to /usr/include?
