* Revamped macro for alignment test
* Fixed a few tests for "long long"s

Nuked FPTOOLS_C_LONG_LONG, AC_CHECK_TYPES already does what we want.

Don't build ltx and sgmlverb, they are unused. With this change, the
test for flex/lex can be removed from the configuration process. The
make rules for flex/lex files are still in mk, but they could be moved
to glafp-utils/mk if someone feels the need for this.

Nuked ancient "msub" stuff and a CVS keyword on the way.

Ooops, forgot about a dozen references to configure.in... :-}

AC_PROG_LEX really checks for the existence of "lex" when "flex" is
not found, so there is no need for AC_PROG_LEX_STRICT.

Furthermore, flex/lex is not really needed for building GHC, so we
issue only a warning instead of dying when flex and lex are not found.

Nuked unused FPTOOLS_PROG_YACCY test and support for yacc/bison in
general. If it is ever needed again, it can easily be resurrected.

Nuked unused FPTOOLS_REGEX_IN_LIBC test

Revamped altzone detection. Note that we test only for successful
compilation now, not for successful linking, but this is what most
autoconf macros do.

* Following the autoconf coding style recommendations, use "#" for
  comments, not "dnl".

* Local macros will get the prefix "FP_" instead of "FPTOOLS_". The
  latter is a bit heavyweight and too fptools-centric.

Nuked unused tests FPTOOLS_HAVE_TIMEZONE and FPTOOLS_TYPE_TIMEZONE

CVS keywords considered harmful

We require at least autoconf 2.50 (not 2.52 and/or 2.53?!)

The autoconf docs talk about "configure.ac" instead of the misnomer
"configure.in" for more than two years now, so let's do the same.

Updated to match latest versions from autoconf repository

x86 OpenBSD moves into ELF land
(and sparc, alpha, sparc64 were already there)

Also, it needs sligtly different header files.

And dlopen can only be called with the DL_LAZY argument on this
system.

OpenBSD has now moved to ELF on x86 architectures.
So mangle it.

OpenBSD x86 has finally moved to ELF.
So it no longer needs a leading underscore on symbols.
However, like FreeBSD, it tries to be friendly, and accept it
anyway. So we have to hard code it.

sparc-*-openbsd mangler

Add canonical form for sparc-*-openbsd*

expandEnvVars.expandString: don't drop prefix when locating variable
reference.

Merge to STABLE.

Sparc Linux configure and mangler

Add support for splicing in foreign exports.

Fix a bug in forkProcess: the current thread should not be on the run
queue while it is running.

Merged from STABLE (1.169.2.1).

Fix a cause of non-linearity when compiling code with large amounts of
static data, such as long lists of integers.

The problem was that CorePrep was calling allLazy on the list of
floated bindings at each level of a nested let, and allLazy runs over
all the bindings floated so far, hence O(n^2) performance.  The fix is
to cache the result of allLazy along with the list of floated
bindings.

Don't require Alex for building GHC (yet).

Reset g0s0->n_to_blocks when using the two-space collector.  Fixes
ever-increasing live data count with +RTS -Sstderr -G1.

Fix terrible bug in isNonPtrRep, which was ignoring the possibily of
the 64-bit reps.  The result was that functions with 2 64-bit args
were getting the wrong argument descriptor, leading to crashes.

Thanks to Peter Thiemann for a great bug report.

Fix the Alex-version-detecting machinery

Add alex to AllProjects

Add DERIVED_ALEX_SRCS to maintainer-clean

Add Alex support.

Detect Alex, and add --use-src-tree-alex option to configure.

Revert part of previous commit that sneaked in by accident.

Fix string gap.

Moved the contents of fptools/happy/alex -r simonm-hackery-branch to
here.  This will become Alex version 2.0 when I've hacked around with
the build and documentation a bit.

- Add -main-is to the flag table
- Sort entries in the linker section alphabetically

Add a note about readline on Win32

punctuation
