These changes require a large set of patches to Genera which are, presently, only
available in the world used by the Intel and ARM versions of Open Genera called
Portable Genera.  (If there's ever a new release of Genera, ...)

These changes add support for the Mezzano operating system and its
Common Lisp implementation. They are based on changes originally
developed by Henry Harrington against ASDF 3.1.7.

The function was removed in 039494bc.

In particular:
 - clasp does not define :ecl
 - use :os-unix instead of :unix
 - use :os-windows instead of :mswindows or :windows
 - use :os-macosx instead of :darwin
 - use :lispworks7+ instead of :lispworks7

Declare a FTYPE for ENSURE-PATHNAME in uiop/pathname so that CCL won't complain
about a forward reference during `make load l=ccl`.

SBCL insists that a type (FUNCTION (T &REST T) T) doesn't cover a function
with keyword arguments, and wants either an exhaustive list of keywords and types,
or a &ALLOW-OTHER-KEYS. So just say FUNCTION, to make SBCL happy, too.

Make ENSURE-DIRECTORY-PATHNAME and TRUENAME* more robust in case
MAKE-PATHNAME throws an error when trying to synthetize a pathname
with components that the implementation considers invalid.

Uncomment the proper definition of LISP-IMPLEMENTATION-DIRECTORY on CLISP,
which now doesn't break asdf-pathname-test anymore.

When using DIRECTORY, the proper pattern to use to get all files
is #p"*" and not #p"*.*" on CLISP and GCL.
This is the opposite of other CL implementations, that
match everything with #p"*.*" and only files without extension with #p"*",
which seems more in line with the CLHS, though counter-intuitive wrt to POSIX.

Now the proper pattern to match all files with TRANSLATE-PATHNAME and
with logical pathnames is still #p"*.*" or #p"*.*.*".

Therefore, we introduce a new parameter *wild-file-for-directory*,
as distinguished from *wild-file*, for notable use with DIRECTORY-FILES.

ccl, gcl, lispworks think that (probe-file #p".bashrc") has its
pathname-name and pathname-type be NIL and "bashrc" whereas other
implementations (at least abcl allegro clisp cmucl ecl mkcl sbcl xcl)
think that it has them be ".bashrc" and NIL.

cl -l $l -i "(let ((p (probe-file \".bashrc\"))) \
(format t \"FOO $l: ~S ~S~%\" (pathname-name p) (pathname-type p)))" \
|& grep FOO

A few are kept, for backward-compatibility with systems in quicklisp.

It's been the official way of calling CMUCL since 2011.

I initially introduced all that make-pathname* madness on the road to
ASDF 2.27, back when I was trying to normalize pathname components so
I may have pathname-indexed entries in the asdf-cache (to minimize
costly filesystem access from file-write-date and such, that could
also introduce inconsistency in the build plan).

Problem is, there was no good way (even non-portable) to normalize
pathnames in a way that works when you use all of parse-namestring,
make-pathname, directory, probe-file, translate-logical-pathname,
merge-pathnames, etc. In the end (as late as b4dc78de, before 3.0.2.13!),
I conceded defeat, for it was an uphill battle, and instead asdf-cache
is indexing things using namestrings instead, which is more stable (see
asdf/cache:normalize-namestring).

The hacks in make-pathname* are therefore not needed anymore,
and the function can be done away with.

This commit guts the contents of make-pathname* and marks it deprecated.
Just use make-pathname instead. It also updates uiop and asdf to not
use make-pathname* but make-pathname. Some future commits may move it to
backward-driver and eventually start issuing warnings of some sort when
it's used.

The JVM doesn't give access to native chdir without some extensions that
aren't available with ABCL. There's a user.dir system property whereby
some Java programs kind of fake it, but ABCL doesn't play nice with it.
Therefore, use *default-pathname-defaults* as our "current directory",
and be sure to chdir to it before to run commands with run-program.
Try to make the run-program chdir feature work on Windows.

On ABCL, os testing is at runtime.
On all other implementations, it's at compile-time.
SBCL can optimize some runtime tests and then complain about unreachable code.
os-cond abstracts over OS conditionalization and makes everyone happy.
Needed by an upcoming configuration change.

Plus minor typographical fixes.

Based on a contribution by Christian Shafmeister.

to speed up search in a source-registry :tree. If you use one, don't let it go out-of-date!

Add a *compile-check* hook for a default compile-check argument.
Also, add back a pathname kludge for GCL until the issue gets fixed.

Everyone should be using a recent 2.7.0 (in ANSI mode) from master for ASDF.

Introduce physicalize-pathname as an abstraction for translate-logical-pathname,
due to bug in CLISP.

relative to said base build directory, for the sake of determinism.

Thanks to Chun Tian (binghe) for his feedback.
MCL has issues with make-pathname failing to override defaults with an explicit NIL component.
