 Log Message:
 Update scheme48 to 1.6.
 Patch provided by Yorick Hardy in PR 36335.
 And added test target (but fail if effective user == root direcoty owner).
 
 Release notes for version 1.6
 
     * Additions:
           o An autogen.sh script for generating the various generated files from source was added.
           o Infrastructure for creating, running and composing test suites was added. As a result, "make check" now runs more tests than before.
           o It is now possible for adventurous users to run the linker in PLT Scheme.
     * Changes:
           o make image now assumes a Unicode-capable Scheme 48.
     * Bug fixes:
           o A bug where automatic port-flushing would churn trying to write to a blocking socket was fixed.
           o An infinite loop upon (/ 0.0 0.0) was fixed. (reported by Taylor Campbell)
           o A bug that made system unusable was fixed. (reported by Marco Benelli)
           o A bug with package mutation, which made running the PreScheme compiler on the VM break was fixed.
           o Bugs related to the conversion between OS strings and strings on command-line handling were fixed. (reported by Andreas Rottmann)
           o Compilation using gcc now uses the -munaligned-doubles flag where available, which is needed on SPARCs to make floating-point arithmetic work.
           o Compilation older versions Cygwin that don't have langinfo.h should be fixed.
           o Some problems with installing and running on Windows Vista were fixed. (thanks to Axel T. Schreiner)
 
 Release notes for version 1.5
 
     * Additions:
           o Comprehensive Unicode support was added. See the manual for details.
           o An implementation of SRFI 19 was added. (thanks to Emilio Lopes)
           o Syntax-rules now supports vector patterns and templates.
           o The ,bound? command now produces more output. (thanks to Taylor Campbell)
     * Changes:
           o Many of the POSIX procedures that accepted or returned strings previously now accept or return OS strings. See the manual for details.
           o The ,build command now accepts a procedure that will be called with a list of OS strings rather than regular strings.
           o The ascii->char and char->ascii procedures from the ascii structure covers only ASCII (codes 0-127) now. (Previously, the range included 128-255 as well.)
     * Bug fixes:
           o A bug with package mutation was fixed. (reported by Taylor Campbell)
 
 Release notes for version 1.4
 
     * Additions:
           o Regexp? is now exported from the rexexps structure.
           o SRFIs 4, 39, 40, 43, 43, 60, 61, 63, 66, 67, 71, 78 (mostly thanks to David Van Horn)
           o In the command processor, switches were generalized to settings, specifically to customize various printing parameters. See the manual for details.
           o A generic byte-code parser was added to the system; the disassembler uses it.
           o A reinitializers for register actions to be performed after resuming an image was added.
           o A variable-arguments-lists structure implementing a macro for dealing with optional default parameters was added.
           o A get-interrupt-handler procedure was added.
           o An --enable-universal-binary option was added to configure to facilitate building universal binaries on Mac OS X. (thanks to Eric Knauel)
           o The C code now has access to enum sets.
     * Changes:
           o File-options (in the POSIX libary) are now enum sets; this allows using enum-set operations on them.
           o Various changes were made to the VM to enable native-code compilation.
           o Socket addresses are always reusable.
           o 1+ and 1- are no longer valid identifiers.
           o The ordering of in/out thunks of dynamic-wind was changed to be consistent with itself and with the upcoming R6RS.
           o The Windows build is now done using Visual Studio 2005.
     * Bug fixes:
           o Macro-defining macros now work in PreScheme.
           o Opening a file for both read and write via the POSIX libraries wouldn't work correctly. (Reported by Andreas Rottmann.)
           o PreScheme's copy-memory! now works for overlapping regions.
           o Various C compilation problems were fixed.
           o cmuscheme48.el should now work under GNU Emacs as well as XEmacs.
           o Numerous problems with floating-point arithmetic were fixed.
           o A race condition with queues was fixed. (thanks to David Frese)
           o Part of script messages were printed on stdout rather than stderr; fixed. (thanks to Andreas Rottmann)
           o A shadowing bug in the debugging package was fixed. (thanks to Taylor Campbell)
           o A bug in the CML sync-group primitive was fixed. (thanks to Heath Putnam)
           o Various errors in SRFI 13 were fixed.
           o A bug in the auto-integrator was fixed. (thanks to Taylor Campbell)
           o A bug in load-dynamic-externals was fixed. (thanks to Taylor Campbell)
           o Several bugs in vector-merge were fixed. (reported by Matthias Radestock)
           o The CML wrap was made correctly tail-recursive. (reported by Heath Putnam)
           o A bug in the PreScheme C backend, that would sometimes incorrectly delete tail calls without a return value, was fixed. (reported by Eric Merritt)
           o Several bugs in interface walking were fixed. (reported by Taylor Campbell)
           o A bug in the PreScheme compiler affecting the removal of unused procedures was fixed. (thanks to Eric Knauel)
