## Yet another hack to support SUN make.
##
## Let's assume 'foo' appears in DISTFILES and is not a built file.
## When building with VPATH=$(srcdir), SUN make and OSF1/Tru64 will
## rewrite 'foo' as '$(srcdir)/foo'.  An attempt to install the file
## with
##    cp $file $(distdir)/$file
## will thus install $(srcdir)/foo as $(distdir)/$(srcdir)/foo
## instead of $(distdir)/foo.
##
## So let's strip this leading $(srcdir)/ when it exists.  (As far we
## know, only SUN make and OSF1/Tru64 make add it.)  Searching whether
## the file is to be found in the source or build directory will be
## done later.
##
## In case we are _not_ using SUN or OSF1/Tru64 make, how can we be sure
## we are not stripping a legitimate filename that starts with the
## same pattern as $(srcdir)?
## Well, it can't happen without the Makefile author distributing
## something out of the distribution (which is bad).  As an example,
## consider "EXTRA_DIST = ../bar".  This is an issue if $srcdir is
## '..', however getting this value for srcdir is impossible:
## "EXTRA_DIST = ../bar" implies we are in a subdirectory (so '../bar'
## is within the package), hence '$srcdir' is something like
## '../../subdir'.
##
## There is more to say about files which are above the current directory,
## like '../bar' in the previous example.  The OSF1/Tru64 make
## implementation can simplify filenames resulting from a VPATH lookup.
## For instance if "VPATH = ../../subdir" and '../bar' is found in that
## VPATH directory, then occurrences of '../bar' will be replaced by
## '../../bar' (instead of '../../subdir/../bar').  This obviously defeats
## any attempt to strip a leading $srcdir.  Presently we have no workaround
## for this.  We avoid this issue by writing "EXTRA_DIST = $(srcdir)/../bar"
## instead of "EXTRA_DIST = ../bar".  This prefixing is needed only for files
## above the current directory.  Fortunately, apart from auxdir files which
## can be located in .. or ../.., this situation hardly occurs in practice.
##
## Also rewrite $(top_srcdir) (which sometimes appears in DISTFILES, and can
## be absolute) by $(top_builddir) (which is always relative).  $(srcdir) will
## be prepended later.

## --------------------------------------- ##
## Building various distribution flavors.  ##
## --------------------------------------- ##

## Note that we don't use GNU tar's '-z' option.  One reason (but not
## the only reason) is that some versions of tar (e.g., OSF1)
## interpret '-z' differently.
##
## The -o option of GNU tar used to exclude empty directories.  This
## behavior was fixed in tar 1.12 (released on 1997-04-25).  But older
## versions of tar are still used (for instance NetBSD 1.6.1 ships
## with tar 1.11.2).  We do not do anything specific w.r.t. this
## incompatibility since packages where empty directories need to be
## present in the archive are really unusual.
##
## We order DIST_TARGETS by expected duration of the compressors,
## slowest first, for better parallelism in "make dist".  Do not
## reorder DIST_ARCHIVES, users may expect gzip to be first.
##
## Traditionally, gzip prepended the contents of the GZIP environment
## variable to its arguments, and the commands below formerly used
## this by invoking 'GZIP=$(GZIP_ENV) gzip'.  The GZIP environment
## variable is now considered to be obsolescent, so the commands below
## now use 'eval GZIP= gzip $(GZIP_ENV)' instead; this should work
## with both older and newer gzip implementations.  The 'eval' is to
## support makefile assignments like 'GZIP_ENV = "-9 -n"' that quote
## the GZIP_ENV right-hand side because that was needed with the
## former invocation pattern.
