Package: gcc-4.1
Version: 4.1.2-13
Severity: normal

"info --node '(gcc.info.gz)Preprocessor Options'" says:

`-MT TARGET'
     Change the target of the rule emitted by dependency generation. By
     default CPP takes the name of the main input file, including any
     path, deletes any file suffix such as `.c', and appends the
     platform's usual object suffix.  The result is the target.

But the behaviour is that the path is stripped. E.g., the following
command:

 "gcc" -MM -I "/usr/lib/ocaml/3.09.2"/caml kernel/byterun/coq_memory.c

gives:

 coq_memory.o: kernel/byterun/coq_memory.c kernel/byterun/coq_gc.h

instead of

 kernel/byterun/coq_memory.o: kernel/byterun/coq_memory.c kernel/byterun/coq_gc.h

Yes. The documentation of -MT says "by default FOO", which I
understand as "if you do not pass an -MT argument, then FOO", as -MT's
role is to override said default. Now that I read the documentation
carefully again, the documentation of -M does indeed document the
actual behaviour, so I suppose this bug becomes "documentation of -MT
contradicts the one of -M and actual behaviour".

Ah. The documentation is correct in 4.3:

 By default CPP takes the name of the main input file, deletes any
 directory components (...)
