New SGML User Guide, first cut.

- intToDigit: if we're going to crash and burn, we might
  as well report back the argument value that caused it.

- NumExts: new hugs&ghc interface
- moved showOct and showHex from Numeric to NumExts

- added regressions tests for Word, Int & Bits
  (pinched test file from Hugs dist.)
- added NumExts regressions tests

buglet (showSDoc, not show)

Added test case for showing Floats and Doubles.

Don't use typecasts to convert floats to ints, use
unions.

Fix interaction of "hiding" on import with "module M" on export

add note about 'make install-doc' to the message printed after
configuration.

protect some sections for the !OMIT_NATIVE_CODEGEN case.

fix script installation *again*.

add note about SGML and the installation guide.

Hmmm, .vsgml rule was wrong.  Not sure how that happened.

add pointer to 3-00-notes.lit.

complete changes list for 3.00.

update for announcement of 3.00.

renameSourceCode: don't emit warnings

Bring back old equality instance for Handles (replaced in rev 1.16) in
the concurrent case, since Eq isn't defined over MVars.

AC_SUBST(exeext)

Better failure message when entering an unimplemented instance method

derived Show instances: Space out comma separated labelled fields

use an explicit primitive integer for minBound::Int to avoid problems
with overloading and negation.

nuke GHC_DEBUG_HILEV_ASM and GHC_GCC_IS_AVAILABLE - never used.

Fix misleading type checker error msgs; fix broken floatBind in Simplify.lhs

cygwin32: Use `native' system() instead of fork() & execl()

Remove reference to tests subdir.

back out last commit, the real test is in drv007.hs.

Finally fix the 'for i in ; do ...' problem.

replace this test with one that actually *fails* on 2.10...

Remove use of lit-lit for minBound::Int, this was only needed for
bootstrapping.

couple of heap size increments from HWL.

hook function for I/O errors

* [cygwin32]: If consistency checker cannot find executable,
  try a little bit harder..

* [cygwin32]: If no output file is given when linking, default to main.exe
* warn about SCCs being dropped when compiling with -prof -auto{-all}

Make output stderr dribble consistent

Changes to reflect Error->GHCerr move

A renamed version of Error.hi-boot

* removed ghc/Error.{lhs,hi-boot}
* moved contents of Error to GHCerr + adjusted
  import lists of files that use old Error functionality.
* moved seqError from Prelude to GHCerr.

* Int and Word rewritten to use unboxed types and operations.
