Ann: SWI-Prolog 5.6.35

Hi.

I've uploaded SWI-Prolog 5.6.35. Quite a few changes, some of which are
important bugfixes. There is also an update version of the stack-shifter
included in the source-code. The stack-shifter hasn't been used for a
long time, but it is planned to reintegrate it to reduce virtual memory
usage for the 32-bit multi-threaded version. Quite a few changes to the
sources are updates to make the stack-shifter work properly. These
changes are incomplete.

Check the changelog below to see whether there are changes that fix
bugs you are faced with.

	Enjoy --- Jan

+++ ChangeLog	6 Jun 2007 13:29:43 -0000	1.1436
+VERSION 5.6.35 (Jun 6, 2007)
+
+  * FIXED: Added lacking library(main) to Windows version.  Win32 installer
+    only; sources and Win64 installer will follow in 5.6.36.
+
+  * FIXED: Posible argument-stack issue, notably associated to destructive
+    assignment.  Tom Schrijver.
+
+  * FIXED: Error in handling signals in Prolog.  Now caused immediate
+    assertion failure due to strickter checking.
+
+  * FIXED: Bug#283 plld.exe sets __WINDOWS__ rather then WIN32.
+
+  * CLEANUP: Avoid using the argument-stack for cycle detection.  Now
+    uses a segmented stack.
+
+  * CLEANUP: Add a new small stack for optimized arithmetic to avoid
+    further overloading of the local stack.  Preparing for re-introducing
+    the stack-shifter.
+
+  * FIXED: Memory leak from GMP constants in optimized arithmetic 
+    expressions.
+
+  * ADDED: PL_INTPTR type to PL_unify_term().
+
+  * FIXED: Avoid error summing CPU time of finished threads.
+
+  * FIXED: Reporting finished threads using current_thread/2
+
+  * CLEANUP: Some cleanup to declarations and stack-shifter, preparing
+    combining the stack-shifter in the normal version.
+
+  * FIXED: memory leak involving GMP numbers for instantiated `output'
+    arguments.  I.e. 0 is 2727 rdiv 22.  Mike Elston.
+
+  * ADDED: Sset_filter() to formalize a filter relation between streams.
+    Incomplete.
+
+VERSION 5.6.34 (April 23, 2007)
+
+  * ADDED: Cross-referencer handles integer arguments in meta-predicate
+    declarations.
+
+  * FIXED: possible scenario where atom garbage collection is no longer
+    automatically started, running out of memory.  Mike Elston.
+
+  * ENHANCED: parse_url(-, +) does not include HTTP port if this is 80.
