install (INSTALL_PROGS): a ; too many

Improved on the install rules for libexecs and bins a little
(at least from a Win32 pov - you can now install "happy.bin"
without trouble.)

Support for generating a VERSIONINFO resource that can be pinned
onto generated DLLs and EXEs (Win32 specific.)

Always prepend `#! $(INTERP)' to a script, even if we're BIN_DISTing.
It doesn't do any harm, and means that we can execute the BIN_DIST
version of a script from the build tree, provided it doesn't depend on
any global paths.

Build System Cleanup
--------------------

This commit is intended to clear the way for automatic RPM building.
In particular, the idea is that 'make install' doesn't build anything,
so you can do

	make install prefix=/some/tmp/prefix

to install everything in /some/tmp/prefix, but leave the hardwired-in
install directories the same.

For scripts that depend on the install dir (currently just the GHC
driver and mkdependHS), we now build two versions: <script>-inplace,
which is used for running the script from the build tree, and
<script>, which is the to-be-installed version.

NOTE: binary distributions are now a little bit trickier to build.
You *must* include the line "BIN_DIST=1" in your build.mk if you
intend to make a binary distribution from the current build tree.
This is because certain scripts have to be built differently, and we
don't rebuild them when doing 'make binary-dist' anymore (since 'make
binary-dist' just does a 'make install' with a re-targetted prefix,
just like the RPM builder).

Other changes

	- the binary-dist machinery is now all in fptools/Makefile
	- removed a gratuitous $(package)-$(version) level of
	  directories from the binary distribution.
	- binary distributions are now placed under the package
	  name, rather than fptools/fptools.
	- various other minor cleanups.

cleanup

- Use explicit file modes when installing binaries & scripts (not essential,
  but someone complained about it).

- Use $(INSTALL_SCRIPT) for scripts

DLL install support

a rule or two for building DLLs

- define and use *_OPTS for the various sgmltools.
- acknowledge the existence of INSTALL_LIB_SCRIPTS.

Move 4.01 onto the main trunk.

quick fix for multi-file sgml docs.

make cleaning -odirs: discard error msgs should rmdir fail

install rule: check to see if SCRIPT_LINK already exists as symlink; if so, delete and create new

New rule, dist-package-zip: package src dists up using zip

only strip libraries if $(StripLibraries) eq "YES"

fix to StripLibraries support.

- New option $(StripLibraries) removes local symbols from library objects.
  Turned off by default, as it only works with linkers that support
  the '-x' (remove local symbols) option.

$(SCRIPT_LINK): use perl to test for symlinks rather than relying /bin/sh 'test'

Handle the case where $(SCRIPT_LINK) already exists (as a file)

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.
