Include config.h.in as well as configure.
Also sets correct owner, group and mode for all appended files.
Update the mtime of all appended files so that configure and config.h.in
are always newer than configure.ac.
(Fixes many problems introduced by 5023ade7, and makes the commit
message actually true.)
For the next release, this means that `autoconf` is no longer required
if building from the tarball. The website and documentation should be
updated accordingly at that time.
This commit hooks the Makefile up to generate a FISH_BUILD_VERSION
symbol and kills off PACKAGE_VERSION in .cpp files.
It also modifies the tarball generation script to add the necessary
version file for releases.
- etc/config.fish and share/config.fish are now "universal" and no longer reference install paths or need to be touched by autotools. They've been removed from config.fish.in to config.fish.
- fish now attempts to determine __fish_datadir and __fish_sysconfdir relative to the path of the fish executable itself (typically by walking up one directory). This means that you can copy the directory hierarchy around and things will still work. The compiled-in paths are used as a backup.
- The fish Xcode project now can build fish natively, without needing autotools.
- Version bumped to 2.0
