protect some StablePtr stuff from __PARALLEL_HASKELL__.

test for newtype declaration with an unboxed field.

couple of newtype changes.

Make it an error for a newtype constructor field to be unboxed (this
would undoubtedly cause problems later on, better to catch it early).

While I'm here, report the context properly for newtype declarations,
it was previously being reported as a 'data' declaration.

revert to version 1.9 of AC_PROG_GNUCPP.

revert 'tr' breakage for the time being.

Back-out fix for layout processing in pragmas.  It broke things.

fixes for errors in last commit.

Several small fixes to multi-param type classes

test for non-layout processing inside {-# ... #-}

Don't do layout processing inside {-# ... #-}.

The fix is horrible, and should probably be redone in a cleaner way at
some point.

clean up old scripts.

Reworded note on the sign extension of shift ops.

added stuff about library re-organisation.

Remove IO exception compat. cruft

checkForModuleExportDups: no need for irrefutable pats

New debug flag: -dshow-rn-imports, dump to stderr the paths to the interface files that are slurped.

- commented out unused code (upp_cc_uf)
- don't include module name when dumping
  scc name inside CC_DECLARE.

Perform UNC->DOS translation on what bash-cygwin32's pwd returns.

delete a spurious space.

Do UNC->DOS translation of TOP_PWD

Re-commit of cygwin32 fix

misc syslib related fixes

Further RAWCPP tweakage

Changed translation of backward slashes to forward ones (now in perl.)

Add a few module from the old HBC lib: they're needed by a couple of things
in nofib.

These can disappear once the dependencies are removed.

correct name of lib.

-syslib conc doesn't have any cbits.

This isn't needed anymore.

remove stray bit of documentation - it was getting in the way of 'make boot'.

alpha-dec-osf1 and alpha-dec-osf3 are now separate configurations.

Warn specially if users should supply interface files
on the command line.

don't substitute TMPDIR when making binary dists (BIN_DIST=1)

Avoid use of system() for simple stuff like touching.

Updated cygwin32 details

Added TMPDIR to list of variables prepended to perl & sh scripts.

AC_PROG_GNUCPP: look for (\/|\\)cpp, not (\/|\\\\)cpp

AC_PROG_GNUCPP: translate backward slashes into forward ones.
AC_HAVE_GCC: tweaked sed regexp to catch cygnus gcc snapshot
version strings (i.e., version cygnus-2.7.2...)

AC_SUBST(exeext) added (only non-empty under cygwin32)

Added entry for assertions
