TIP#72 implementation. See ChangeLog for details.
This version builds clean on Solaris/SPARC, with GCC and CC, both with and without threads and both in 32-bit and 64-bit mode.

+ +----------------------+
+ | TIP #72 IMPLEMENTED. |
+ +----------------------+
+
+ There are a lot of changes from this TIP, so please see
+ http://purl.org/tcl/tip/72.html for discussion of
+ backward-compatability issues, but the main ones modifications are
+ in:
+
+ * generic/tcl.h: New types.
+ * generic/tcl.decls: New public functions.
+ * generic/tclExecute.c: 64-bit aware bytecode engine.
+ * generic/tclBinary.c: 64-bit handling in [binary] command.
+ * generic/tclScan.c: 64-bit handling in [scan] command.
+ * generic/tclCmdAH.c: 64-bit handling in [file] and [format]
+ commands.
+ * generic/tclBasic.c: New "wordSize" entry in ::tcl_platform.
+ * generic/tclFCmd.c: Large-file support (with many consequences.)
+ * generic/tclIO.c: Large-file support (with many consequences.)
+ * compat/strtoll.c, compat/strtoull.c: New support functions.
+ * unix/tcl.m4, unix/configure: 64-bit support and greatly enhanced
+ cacheing.
+
+ Most other changes, including all those in doc/* and test/* as
+ well as the majority in the platform directories, follow on from
+ these.
+
+ Also coming out of the woodwork:
+ * generic/tclIndex.c: Better support for Cray PVP.
+ * win/tclWinMtherr.c: Better Borland support.
+
+ Note that, in a number of places through the Unix part of the
+ platform support, there are Tcl_Platform* references. These are
+ expanded into the correct way to call that particular underlying
+ function, i.e. with or without a '64' suffix, and should be used
+ by people working on the core in preference to the API functions
+ they overlay so that the code remains portable depending on the
+ presence or absence of 64-bit support on the underlying platform.
+
+ ***POTENTIAL INCOMPATIBILITY***: Extracted from the TIP
+
+ SUMMARY OF INCOMPATIBILITIES AND FIXES
+ ======================================
+
+ The behaviour of expressions containing constants that appear
+ positive but which have a negative internal representation will
+ change, as these will now usually be interpreted as wide
+ integers. This is always fixable by replacing the constant with
+ int(constant).
+
+ Extensions creating new channel types will need to be altered as
+ different types are now in use in those areas. The change to the
+ declaration of Tcl_FSStat and Tcl_FSLstat (which are the new
+ preferred API in any case) are less serious as no non-alpha
+ releases have been made yet with those API functions.
+
+ Scripts that are lax about the use of the l modifier in format and
+ scan will probably need to be rewritten. This should be very
+ uncommon though as previously it had absolutely no effect.
+
+ Extensions that create new math functions that take more than one
+ argument will need to be recompiled (the size of Tcl_Value
+ changes), and functions that accept arguments of any type
+ (TCL_EITHER) will need to be rewritten to handle wide integer
+ values. (I do not expect this to affect many extensions at all.)
