>Description:
gcc -M now outputs the full pathname to the source file
rather than the basename.  This can break source trees
that separate obj & src code and do automatic
prerequisite generation.  The object files now end up in
the source tree.
>How-To-Repeat:
Untar attachment.  cd into dep/obj.  Update
Makefile to point to a recent gcc 2.97. Run make.  The
object will be in the source directory.  Repeat
with gcc 2.95.2 (for example) and it will work ok--
the dep.o file will be in the obj directory.
