Ooops, forgot to rename version.mk in my previous committ...

Make tests run on Cygwin hosted MinGW32 build.

Use version info from configure.ac

Use some sed magic to avoid PACKAGE_FOO clashes introduced by the autoconf
cleanup yesterday. Another option would have been using a plain "AC_INIT" in
fptools/configure.ac (and probably the same for fptools/libraries/configure.ac),
so only "leaf configure.ac"s have package info. Not quite sure what would be the
nicest way to handle this yet...

Make autoupdate 2.52 happy, mainly by using the new formats of AC_INIT and
AC_OUTPUT. This has the nice side effect that all "packages" have now a name, a
version, a bug-report address, and a tar name, yielding better output with
"configure --help=recursive". Nuked an unused AC_STRUCT_ST_BLKSIZE test on the
way.

Remove debugging trace that I left in when working on mk_switch.

New option, -P, turns off line pragma emission

Collect unknown chunks in new chkcat 'unknown' which gets treated like
'misc', but isn't mangled on sparc-*-solaris2 because of function
definitions in C-headers like <pwd.h>. This shouldn't affect any
other platform since this was already a border-case.

Closes SF Bug 1012521 "getUserEntryForID dies".
Please merge.

On Windows default to main.exe instead of a.out.

arrow notation: allow arrow applications (f -< a) to take a non-empty
command stack, as suggested by Sebastian Boldt <Sebastian.Boldt@arcor.de>.

- Remove configure tests for SIG{POLL,INFO,WINCH}:
  Testing via #ifdef SIGFOO should be sufficient.
- Change #if HAVE_SIGPOLL to #ifdef SIGPOLL
- Remove SIGINFO/WINCH from package base: they'll reappear in package unix
  in System/Posix/Signals.Exts.

Oops, fix bugs in previous commit.

Add a couple of cases to mk_switch to catch the case when we have a
tag range that has a lot of default cases at either end, and we're not
using a single switch.  In situations like this we want to eliminate
the default cases with an if-statement, before dealing with the rest
of the branches, which might then be suitable for a switch.

Also, ignore empty tag slots at either end of the range if there is no
default case.

This might work around a gcc 2.95 bug that we tickled with the
code being generated before.

Accept '#pragma' lines in the cmm parser.
This is necessary because Apple's version of GNU cpp 3.3 leaves #pragma
lines in it's output, which cause the build to fail on Mac OS X with
GCC >= 3.3

Fixed "yes" vs. "YES" confusion. This is currently really a mess and I'll
really have to clean this up someday...

* Merged stgMalloc and execPage into a single function which handles
  even multiple pages correctly.

* Enabled the use VirtualProtect on x86 WinDoze now. This could be
  necessary for processors which distinguish between READ and EXECUTE
  memory accesses, e.g. Itaniums IIRC.

* Nuked pageMode and set page permissions always to READ/WRITE/EXECUTE,
  otherwise we could accidentally remove the WRITE permission.

Only mildly tested on x86 Linux, but it might be worth merging into
the STABLE branch when it turns out to work on x86 WinDoze and OpenBSD.
SimonM?

Replace prog_belch with errorBelch.

Improve fop detection now that SuSE has fixed their broken /usr/bin/fop

threadSqueezeStack(): with DEBUG, zero out entire payload when
blackholing. Required now that LOOKS_LIKE_INFO_PTR() isn't 100%
precise.

Merge to STABLE

printClosure(): handle MVARs

There was a missing $T_HDR_info setting for solaris2/openbsd.

malloc memory isn't executable by default on OpenBSD, so mprotect
pages in execPage for that platform. Enables the FFI.

Merge to stable

Warning police. Why is x86_init_fpu disabled, BTW?

Nuked "Revision" CVS keyword

Removed the annoying "Id" CVS keywords, they're a real PITA when it
comes to merging...

NOINLINE is mentioned in the H98 report, not NOTINLINE.

MERGE TO STABLE.

Unbreak previous commit. Is QA on holiday? :-)

RtsShouldNeverHappenCode never happens, now.

Fix problem that shows up when building stage2 on Windows: slots of a
vector table that can never happen are normally filled with the
RtsShouldNeverHappen label, which currently prints as "0".  On systems
with leading underscores on labels, such as Windows, this turns into
"_0" which is reported as an undefined symbol.

Having a label print as "0" is a real hack, so the solution is to do
it properly.  This commit does just that.

Another SrcSpan fix: the span of a Match now covers the entire equation, not
just the rhs.

Update to previous commit: avoid non-portable features of test(1).  It
looks better this way, anyway.

Fix bug in decode_tuple (fixes tc177(prof))

Fix apparent typo in call to debugBelch; Win32 only I think

Move forkProcess()-prototype to RtsExternal.h where package unix can see it
(avoids an 'implicit declaration' warning there)

Fixed FP_LEADING_UNDERSCORE macro, removing the need for a special handling
of Mac OS X again.

Unified the comments in (almost) empty aclocal.m4 files

Added case to FP_LEADING_UNDERSCORE macro for darwin platform.

Fix newline wibbles in new message API

Minor updates required by VS: return the typechecker's abstract syntax
tree from hscBufferFrontEnd.

Add cpp-protected signals sigINFO & sigWINCH if available.
(An autoconf-wizard might want to look at the bottom of configure.ac, the
similarities between HAVE_SIGPOLL, HAVE_SIGINFO & HAVE_SIGWINCH can surely
be factored out)
