From 76a2fc5c3fa8edb17a6e9e15d5ef519768f9ccff Mon Sep 17 00:00:00 2001

Subject: [PATCH] makedepf90: Adds the '-B PATH' option to mirror src directory
structure in object PATH.
When working on one of my projects, I wanted to preserve the directory
structure used in the source tree within the objects PATH. The main
issue was naming collisions with the '-b' option, since I have
sub-directories within the source tree and some of the files have the
same name resulting in the same objects within PATH. So '-B' behaves
similarly to '-b', but places resulting objects within PATH using the
same directory structure as the source files. The motivation for this
addition is to be able to have equivalent source file names contained
within different directories and still use the same top level objects
PATH.
