Missing Show instance for FreeRegs on PowerPC

Wibble to printing FunTyCon in GHCi that makes :b GHC.Base work

Marginally improve the error message on a failure in DsMeta

Tiny fix to patterns with type sigs

Allow trailing parens in GADT signatures

	Make deriving work for infix constructors

	Merge to stable branch

Back quotes were not being done correctly in deriving Read and Show.
Now they are.  I think.

Test is drvrun018

Avoid building the GHCi version of this lib

Use standard calloc rather than rolling our own.

As a small bonus, the standard libc version is more effecient about zeroing
the memory.

Linker.c: linux/ppc: We call mmap() to allocate additional pages to
                     create jump islands.  In the case where no
                     additional memory was needed the mmap call was
                     being made with a size of 0 which would fail.
                     The call is now conditionalised and documentation
                     has been added to the code.  Closes trac #439.

ignore _darcs

fix missing symbol

Raise the (new) exception NestedAtomically when atomically is nested
(using unsafePerformIO).  This is a small improvement over crashing.

fix FAQ links

the FAQ is now in the Wiki

while I'm here, bring various other bits of this page up to date

Update bug reporting instructions to point to the new bug tracker

Update the bug reporting instructions, I've now installed a redirect from

  http://www.haskel.org/ghc/reportabug

to the bug reporting instructions, just in case we want to move that
page in the future.

In the panic message, point to the bug reporting page in the User's
Guide rather than directly to the bug reporting page.  That way people
will see the bug reporting instructions as well as the direct link
(which has now changed).

Make the front panel compile again, submitted by Duncan Coutts
<duncan.coutts@worc.ox.ac.uk>.  From his email:

Attached is a patch to port the GHC RTS font panel to Gtk+ 2.x rather
than the obsolete Gtk+ 1.2.

There were basically two changes needed. Change the configure check to
look for the pkg-config utility rather than the old gtk-config. At it's
just checking for Gtk+ 2.0 or later. It may be that the new code
actually needs a slightly later version than that. I'm not quite sure.

The other change was to convert the ghc-fontpanel.glade file to the
glade-2 format using the libglade-convert script and then to re-generate
the C code for constructing the GUI, that is the Vis*.c Vis*.h files in
ghc/rts.

The front panel has been bit-rotting for quite some time so it has not
kept up with changes in the rts structures. So I had to comment out
references to 3 bits that no longer exist. I've left FIXMEs in the code
at the appropriate places so that someone wiser than me can make the
appropriate changes.

So the thing does now build though I have no doubt that it will not run,
or at least will not do the right thing because it has not yet been
updated to the current state of the rts. However hopefully now that it
is at least buildable with a modern Gtk+ version someone else might be
able to fix it up.

This also relates to trac ticket #599:

http://cvs.haskell.org/trac/ghc/ticket/599

remove one mention of hslibs

- remove hslibs link
- add Building Guide link
- remove the word "hierarchical" from "hierarchical libraries"

revert rev. 1.22 again, just in case this is the cause of the
segfaults reported on OpenBSD and SuSE.

Fix Windows build

fix bug in the case of an uncaught exception

check for overrun of the fd_set, some OSs give you more descriptors
than FD_SETSIZE

-----------------------------------------
	Fix 'mkName' operator in Template Haskell
	so that it handles built-in syntax
	-----------------------------------------

	Merge to stable branch

The 'mkName' function in Template Haskell wasn't dealing correctly with
built-in syntax.  The parser generates Exact RdrNames for built-in syntax
operators, such as ':' and '[]'; and hence so should Convert.

At the same time I'm now generating a better error message in TH when
you use a constructor as a variable or vice versa.

small tidyup for printing bindings with long identifiers: allow the
binder and its definition to go on separate lines

Small performance improvement to STM: reduce the size of an atomically
frame from 3 words to 2 words by combining the "waiting" boolean field
with the info pointer, i.e. having two separate info tables/return
addresses for an atomically frame, one for the normal case and one for
the waiitng case.
