>Description:
The "-include" option of gcc built from the tip searches
relative pathnames from the implicit directory specified
by the source file directory, and not the current 
directory.
>How-To-Repeat:
To reproduce, make sure you're using a shell that doesn't 
expand the "../" in the command line (tcsh happens to do
this).  Then follow these steps:

% touch foo.h
% echo "int i;" > foo.c
% mkdir foo
% cd foo
% gcc -v -c -include ../foo.h  ../foo.c
