Makes db2html from db2html.sh

db2html is now produced from db2html.sh

3rd time lucky with DIET_HEP and Cygwin.  I hope.

Rename DietHEPpish things HMODULE, GetProcAddress, etc, since those
names conflict with Windows builtins.

compile PrelRules with -fvia-C for now.

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).

Minor wurbles to make it compile on Cygwin following DietHEPpery.

Update for changes in the profile output.

The time/allocation profile now shows costs as both

	- "individual" (incurred by the specific cost-centre stack), and
	- "inherited" (incurrent by the cost-centre stack and all its
	  children).

In addition, the "inner" column has been removed (should be the same
as the sum of the scc counts of the children of the current node), and
the "caf" column has been removed (wasn't very useful).

Clarified comment about SGML_TOP.

Changed absolute paths to use SGML_TOP.

Added docbook.

add some #ifdefery to suppress warnings.

Upped minimum version of GHC required to use new PrelAddr to 405.

First try at support for DietHEP.  Has some unfindable bug which causes
it to fail when hugs.c is compiled -O; works fine without -O.

Remove reference to dLL_ifs.hi (was being specifically ignored  in
preprocess_include_dirs).

Fix install rules for _imp libraries under Windows. They must only be
installed if EnableWin32Dlls is YES, but not in the dll way (otherwise
a spurious _dll is inserted into the library name).

integerToWord64 only started working properly yesterday (!), so don't
include folding on word bitops in pre-4.07 GHCs.

Don't try to install import libraries if way /= dll

versionitis: pre-4.06 GHCs didn't have PrelAddr.intToWord

Rename From*Bounded functions to boundedFrom* for consistency with
numericFrom*

Corrected use of patsubst.

add links to FFI stuff.

First cut at 4.07's release notes.

Added rules for constant folding with the folloging ops:
WordQuotOp, WordRemOp, AndOp, OrOp, XorOp, Int2AddrOp, Addr2IntOp,
Float2IntOp, DoubleNegOp, Double2IntOp, Double2FloatOp, Float2DoubleOp

Try to avoid clashes with files already in $TMPDIR.

Don't open with O_NONBLOCK, instead open in blocking mode and set
O_NONBLOCK subsequently with fcntl().  This appears to fix the
problems with FIFOs.

Pick one of the following:

	- the semantics as implemented by Linux & Solaris is broken
	- the POSIX semantics is broken
	- our expectation that things should behave sensibly is unreasonable

Make gmp DLL in DLL way (wasn't being made at all before).

StablePtrRep is now more like a pointer than an integer, so use the
correct union tag when assigning one to a register to avoid warnings.

Fix installing for DLLized Windows build.

Removed dLL_ifs.hi from INSTALL_DATA under Windows (no longer exists).

Wibble...

The corrected example is as follows:

myS :: (forall t t1 t2. (t -> t2 -> t1) -> (t -> t2) -> t -> t1)
[NoDiscard] __AL 3
myS
  = \ @ t @ t1 @ t2 f :: (t -> t2 -> t1) g :: (t -> t2) x :: t -> f x (g x)

public class myS implements Code {
  public Object ENTER () {
    VM.COLLECT(3, this);
    final Object f = VM.POP();
    final Object g = VM.POP();
    final Object x = VM.POP();
    VM.PUSH(x);
    VM.PUSH(new Thunk(new myS$1(g, x)));
    return f;
  }
}
class myS$1 extends Code {
  final Object g;
  final Object x;
  public myS$1 (Object _g_, Object _x_) {
    g = _g_;
    x = _x_;
  }
  public Object ENTER () {
    VM.PUSH(x);
    return g;
  }
}

First attempt at at class lifter for the GHC GOO backend.

This included a cleanup of the Java/GOO abstract syntax
  - Name is now a string, not a list of string
  - Type is used instead of name in some places
      (for example, with new)
  - other minor tweeks.

---------
Example for myS f g x = f x (g x)

public class myS implements Code {
  public Object ENTER () {
    VM.COLLECT(3, this);
    final Object f = VM.POP();
    final Object g = VM.POP();
    final Object x = VM.POP();
    VM.PUSH(x);
    VM.PUSH(new Thunk(new Code(g, x)));
    return f;
  }
}
class myS$1 {
  final Object g;
  final Object x;
  public myS$1 (Object _g_, Object _x_) {
    g = _g_;
    x = _x_;
  }
  public Object ENTER () {
    VM.PUSH(x);
    return g;
  }
}

Reinstate the bytecode peephole optimiser.

findFilesForModule: search default library directories before looking
at user-supplied search paths.

More RULES for coercions and truncate.

Temporarily removed i018 test on mingw

Omitted some tests on mingw.

Omitted some tests on mingw (conc020 *should* work, but doesn't).

compile CType.lhs via-C, since the NCG's register allocator seems to
behave suboptimally when presented with the huge switch in this file.
