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.

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).

/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

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

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

Added FIND as a symbol so that it can be changed on OSes which have
different ideas as to what "find" should do.

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.

Set SRC_SGML2XXX_OPTS variables rather than SGML2XXX_OPTS

Added SGMLSTYLESHEET variable and set SGML2XXX_OPTS to -d $(SGMLSTYLESHEET)

Changed rules to make SGML documentation using DocBook tools rather than
LinuxDoc.

Set MKDEPENDHS to $(HC) instead of $(GHC).
This means that dependencies will be computed with the same
compiler as compilations, which is presumably the right thing.

Add comment about TMPDIR.

remove old unused $RTS_PREFIX I just noticed.

eliminate recursive defn: HC <--> WithGhcHc

New make variable: $(WithNofibHc) which defines the Haskell compiler
used to build nofib.

Define $(GHC_INPLACE) in fptools/mk/config.mk.in.  $(WithNofibHc) is
set to $(GHC_INPLACE) by default.

Fix $(MKDEPENDHS) in ghc/lib/std/Makefile.

Automatically detect installed copies of ghc, nhc and hbc and plug
them into the Makefile variables $(GHC), $(NHC) and $(HBC)
respectively.  $(HC) is now supposed to be a generic installed haskell
compiler, which defaults to $(GHC) and can be changed via ./configure
--with-hc=<blah>.

Reorganise and tidy up a few things in config.mk.in.

80-columnify

Add hslibs to the default $(ProjectsTo{Install,Build})

Add checks for readline library (as opposed to headers).

Add way 's', for SMP/PThreads

set $(HC) to the inplace ghc driver script.

--with-ghc-hc is now --with-hc (to be used as the "locally installed
Haskell compiler" for all projects).

Remove some unused things.

oops, forgot to commit this yesterday.

RAWCPP is now '$(CPP) -undef -traditional'.

Typo from Wolfram.

Make use of the $(GhcWithRegisterised) build flag from config.mk.  You
can now get an unregisterised build by *either*

	- setting GhcWithRegisterised to NO in build.mk, or
	- adding 'u' to GhcLibWays.

The former will make all compilations unregisterised, whereas the
latter will require a '-unreg' flag to be passed to the compiler to
get the unregisterised build.

Pass -unreg for unregisterized builds.

added a new way (dll) to use when building Prelude DLLs
