This is actually from the first non-empty, non-comment line in
/etc/profile, where the (converted) windows path is prepended with
"/usr/local/bin:/usr/bin:".  This suggests that the PATH as seen by bash
starts life with that dot appended, but of course it would be more
conclusive if the OP had shown the complete output (and maybe truncated
the windows PATH variable for the experiment).  Looking at the visible
PATH it is quite likely that this variable is rather long and the rest
of the environment may be quite large also.  There are interesting
problems when one or both of these get over a certain size – like for
example Git, which is using environment variables quite extensively,
stopping to work correctly without giving any useful error messages.  It
probably isn't the problem in this case, but the spaces and parens in
the windows path also can become a problem when scripts aren't super
careful with their quoting.


Regards,
Achim.
