           Summary: Documentation Bug of the "-B" option
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: other
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: harald at redhat dot com
                CC: gcc-bugs at gcc dot gnu dot org

from the info page:
>      The compiler will check to see if the path provided by the `-B'
>      refers to a directory, and if necessary it will add a directory
>      separator character at the end of the path.

This is not true... it seems to work only if a / at the end is appended to the path.

It works for me on the mainline with and without the slash at the end.  It also works for me in 3.3.
What do you mean by not working?
Here is my invoke, you can see clearly it works:

This is not how -B worked in gcc < 3.0: The argument of -B is supposed to be a 
simple prefix, so that -Bfoo will find foocc1, fooas, foold, etc (no path 
search).

So what I am understanding is that Harald is using a GCC whose version is less than 3.0 
and he is reading the manual (info page) for a 3.2.2 based one.  Is that right Harald or is 
that the 3.2.2 you are using a redhat version which reverted this what 3.0 used to do?

ooops, I forgot, this is the old gcc 2.96 (redhat), and I read the new info
pages... sorry.
