In the gcc info pages the documentation for -M and -MT appears to contradict 
each other as to what the target name should be by default:

`-M':
  [...]
  Unless specified explicitly (with `-MT' or `-MQ'), the object file
  name consists of the basename of the source file with any suffix
  replaced with object file suffix.

`-MT TARGET':
  [...] By
  default, CPP takes the name of the source file, including any
  path, deletes any file suffix such as `.c', and appends the
  platform's usual object suffix. The result is the target.

My understanding is that the `basename' (used in -M doc) is the filename 
without the path. 
My experience also shows the real default behaviour is the one described in -M 
description, not in -MT description. (tested on 2.95 and 3.3.3)

I, for one, would like the behaviour described in -MT.

So this bug report includes:
- a documentation error.
- a request for a new -Mx directive to use filename including path for default 
target name.

Thanks
