-Subject: [PATCH] FEATURES=case-insensitive-fs for bug #524236
-
-When case-insensitive-fs is enabled in FEATURES, the dblink.isowner
-method, _owners_db class, and ConfigProtect class will be
-case-insensitive. This causes the collision-protect and unmerge code
-to behave correctly for a case-insensitive file system. If the file
-system is case-insensitive but case-preserving, then case is preserved
-in the CONTENTS data of installed packages.

-    
-    relative install_names (@..../) will be used in binaries a lot, and if
-    they are provided as such, there is nothing wrong with it.  Since they
-    disallow us to do any checks, we just do the least check we can do,
-    which is for the install_name self-reference.  We want to find the
-    library that points to in the install image, if not, it must be wrong.

-There are still some scripts in 2.2.7 that need to get the shebangs fixed:
-$ git grep '#!/'

-Thanks!

-Subject: [PATCH] econf: multijob-safe shebang tweaking
-
-Using econf in parallel for multiple configurations (multilib, or
-ncurses' wide+narrow), both may try to fix configure's shebang.
-On Cygwin at least, this may cause 'sed -i' to fail with:
- sed: cannot rename /.../work/ncurses-6.0/sedXZsjI6: Permission denied
-Instead of 'sed -i', better use 'mv -f' towards the original file.
