Make sure DLL_NAME only has DLL_PEN prepended if DLL_NAME has already been
set, i.e. a DLL is really to be built.

Target dlls directly into DLL_PEN so that they don't get rebuilt all the time.

Move DLLs to $(DLL_PEN) after generation.

mkdependHS doesn't understand the -o option anymore; instead it grokss
ghc's -osuf option.  We never really used this, and it behaves
strangely when mixed with -s, but at least now it doesn't conflict
with GHC's -opt<blah> options.

* SGML_DOC can now hold a _list_ of sgml documentations to build
* both building.sgml and ffi-art.sgml are now build in docs/

*MERGE*

Put back the '$(RM) $@' in the rule for building library modules when
splitting, until we fix this problem properly.

Removed info and texinfo support.

Further cleanups to the clean targets.  Don't recurse too much for
distclean and maintainer-clean.

sort out the clean targets.

- veryclean has gone away (don't know where it came from in the first
  place)

- the clean targets are now

	mostlyclean <= clean <= distclean <= maintainer-clean

Improved rules for stubs. Not perfect yet, but better than before.

wibble

- Don't rm the .o file when splitting.   Doing so
  forces grotesque amounts of recompilation

- actually add -split-objs to SRC_HC_OPTS if $(SplitObjs) == YES and
  we're building a library.

- collect together all the $(SplitObjs) stuff in one place under
  the library building code (it's only relevant for libraries).

SplitObjs=YES should now work.

Move the HC_PRE & HC_POST stuff into target.mk, so we can override
SplitObjs in the Makefile properly.

Add $(INSTALL_INCLUDES), we'll probably need it at some point.

Fixed -split-objs and removed last vestiges of dLL_ifs.hi.

find changed to FIND, that Windows users may
ignore DOS find when PATH has gone astray.

Replaced $(HC_OPTS) in mkdependhs rule whence I had inadvertently removed
it along with the odir filter in which it sat.

Added SplitObjs for when -split-objs is being used. Removed -split-objs and
-odir from GhcLibHcOpts. -odir shouldn't be needed any more in any case.

Changed order of recursive makes so that recursive make happens before make
in the current directory. This helps when building hslibs as DLLs, where
the cbits DLLs need to be made before the main DLLs.

Add $(SGML_DOC).tex to $(CLEAN_FILES).

cleanups & fixes

Obtained-from: Michael Weber <michael.weber@post.rwth-aachen.de>

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'
