Handle the case where  already exists (as a file)

- Moved `dist' rule that sets up SRC_DIST_FILES symlinks past
  the recursive `dist' rule that creates the shadow dist tree.
- Experimental support for aliases in SRC_DIST_FILES lists, i.e.,
  foo~bar will create a symlink from `bar' in the dist tree to
  `foo' in the build tree (useful for the cases where you're
  shipping Makefiles that differ from the fptools/ ones.)
- New target `dist-manifest': create MANIFEST files for a
  (source) distribution.

fix 'make -k' again :-)

Replace uses of 'set -e' with explicit checks for process return codes

don't recurse over the different ways with `make runtests' inside leaf
directories, leave that to `make all'.

- TAGS rule: be quiet if we fail to copy generated TAGS file
  from build to source tree.

Add support for links to versioned driver scripts.

Remove old literate documentation support, and add support for
multi-file SGML documents.

Even more gruesome hack to avoid -odir $* problems in make depend.

Remove cruft to do with running mkdependHS directly, and add cruft to
deal with running 'ghc -M' with HC_OPTS that includes $*
(eg. GhcLibHcOpts).

forget it; there's no portable way to install a link.

add INSTALL_BIN_LINKS for linking things in $(bindir)

remove some superfluous-looking parenthesis around a test.

another attempt at getting 'make -k' to do the right thing.

build SGML documentation using the normal 'gmake dvi' etc.

project-ify the bin-dist rules a bit.

add lengthy comment about recursive makes and failure.

fix the set -e business again.  I could have sworn I'd already done
this.

prune #* and .#* when making source dist.

protect $$s for bash.

Fix the 'set -e' business for subdirectories.  Too late for 2.08
unfortunately.

- do $(SCRIPT_SUBST) properly for shell scripts.
- don't bomb out if the rmdir fails when cleaning split_objs
directories.

Use exeext; removed non-#! support for cygwin32 (no longer needed)

stop-on-error behaviour for recursive rules

remove superfluous braek introduced in rev.1.16.

Improved TAGS support

ranlib installed libraries if needs be

Added hooks to have multiple object suffixes for make depend

More portable use of grep

Reverted back to use of #! in perl scripts on non-cygwin32 platforms

Improved test for how to invoke makedepend script on Haskell source

hash-bang scripts

ghc-2-03-p1 merged onto main trunk

Typos + leave out tests/ in src-dists

merge from 2.02 branch

Further install rule fiddling

Debugged install rules

minor fixes before 2.02

Pretty-print recursive rules

Still moving towards 2.02
