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.

Added -dll option for dll way, now a proper way.

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

Changed ExeSuffix to exeext (which is what configure.in actually calls it).

Add $(EXE_SUFFIX) to hp2ps and unlit

Move dlls to $(DLL_PEN) after generation.

Move DLLs to $(DLL_PEN) after generation.

Pass flags -agc to $(HAPPY) if the $(HAPPY_VERSION) is >= 1.8
(previous versions weren't reliable enough with these settings).

Check the version of the installed ghc, and set GhcVersion,
GhcMajVersion, GhcMinVersion and GhcPatchLevel make variables.

Add test for GNU regex in libc, which we'll use to decide whether to
compile our own copy of the library in package text.

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*

autoconf hackery for CTypes{,ISO}

The DocBook saga continues: Look for already installed catalog first.

Always run docbook scripts with the catalog as the first argument (taken
from DOCBOOK_CATALOG).

Autoconf magic to determine a working DocBook CATALOG file (if any).  Makes
the makefile variable DOCBOOK_CATALOG refer to this CATALOG file (absolute
path).

Build hslibs first if we're bootstrapping from .hc files.

cosmetic only

Add JadeCmd to find path of jade.

Removed the SGML directories stuff. This should all be set up by the user
(who won't have to if the SGML tools are correctly installed).

Clarified comment about SGML_TOP.

Removed LITERATE, added DOCBOOK_PREFIX, and improved some comments.

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

Removed info and texinfo support.

Point out in the comment for GhcLibHcOpts that it also applies to the
standard library and hslibs.

Typo: changed ($Var) to $(Var) in test to set SplitObjs.

Replaced SGML2INFO stuff (which is no longer supported) with SGML2PS (which
is, and may well be useful to some).

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

/tmp/msg

Further steps towards an empty build.mk:
   * GHC is now built with -O by default
   * hslibs/tools now use GhcLibToolsHcOpts, again -O by default

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.

Make splitting object files the default again on non-Windoze platforms

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.
