     I actually wasn't aware that recent GCC had changed the way it
     treats bare -I.  I know that -I- is now deprecated in favor of
     -isystem.
     
     Maybe you can explain further?

-I- actually did two things. From the gcc-3.3.5 documentation :

           In addition, -I- inhibits the use of the directory of the current
           file directory as the first search directory for "#include "file"".

It probably wasn't a good idea to have one flag serving two purposes. But
it seems that in gcc 4.x, there is no way to specify such an
inhibition.  I don't think this particular issue is going to affect
the PSPP build system, unless it's compiled using a virtual view
path.  But it got me worried ...
