 Based on patch provided by Aleksej Saushev in PR 36471.
 
 pkgsrc changes:
  Enable to build x11 feature (optional, default=on).
  Previously, depend on x11, but not build x11 feature.

 Richard Harke ported SCM to the Linux-ia64.
 
 SRFI-94 Type-Restricted Numerical Functions.

 Radey Shouman has changed LETREC to behave like LETREC*:
 
   * eval.c (ceval_1): Change LETREC behavior to that of LETREC*:
   initializers are run in left to right order, and may use
   previously evaluated variables bound in the same contour.  This
   change also applies to LETRECs resulting from internal DEFINE.
 
   * eval.c (macroexp1): Add #ifdef to switch case handling line numbers
   in ceval_1 so that they are safely discarded when MEMOIZE_LOCALS is
   not #defined.  Perhaps line number generation should be disabled in
   that case.
 
   * scl.c: Changes to allow compilation with MinGW (gnu-win32);
   asinh, acosh, and atanh are not yet supported.
 
 From Aubrey Jaffer:
 
   * indexes.texi (Indexes): Give each index its own node when not in
   info mode.  Moved index stuff here so it doesn't break
   texinfo-every-node-update.
 
   * scm.texi (Index): Replaced nodes under Indexes with node Index
   when in info mode; fixes indexing in Emacs 21.4.1.
   Converted to use @copying.
   (Indexes): Reorganized.
   (Data Type Representations): Corrected pattern for specfun and cclo.
 
   * byte.c (subbytes): Added.
   (scm_subbytes_read, scm_subbytes_write): Renamed from substring.
 
   * Makefile (dscm4, dscm5): != is string operator in shell.
   "mv -f" for previous scm, slibcat, and implcat.
 
   * Init5e2.scm (boot-tail): Don't load ScmInit.scm if *script*.
   (string-index, read-line): Defined for login->home-directory, which
   may be called before REQUIRE is defined.
 
   * Makefile (dscm4, dscm5): Added randomize_va_space machinations.
   (dvi, pdf): New tetex-3.0(-20.FC5) broke them -- fixed.
   (SETARCH): Workarounds allow dumping in recent Linux.
 
   * time.c (linux): defined CLKTCK to (sysconf(_SC_CLK_TCK)).
 
   * repl.c (scm_read_numbered): Don't #ifndef MEMOIZED_LOCALS.
 
   * build.scm (dont-memoize-locals): Added feature.
   (stack-limit): Removed feature.
 
   * scmfig.h (STACK_LIMIT): Always defined.
   (CHECK_STACK): Condition on scm_verbose.
 
   * sys.c (stack_check): Always present.
 
   * Makefile (docs): Added target to make all documentation files;
   then invoke xdvi.
 
   * ugsetjmp.s (_setjump, _longjump): For Ultrix VAX circa 1997.
 
   * subr.c (mkbig, adjbig): Improved overflow message.
 
   * mkimpcat.scm (wbtab, rwb-isam): moved to "Simple associations".
   (add-source): Use 'source form and check file's existence.
 
   * scl.c (scm_magnitude): Extend dynamic range by eliminating
   intermediate expression swell.
   (divide): Use "Smith's formula" to extend dynamic range;
   but makes an insignificant difference when compiled with -O3.
   (atanh, acosh, asinh): define if #ifndef HAVE_ATANH.
 
   * scmfig.h (HAVE_ATANH): Decides whether atanh, asinh, and acosh
   are supported.
 
   * r4rstest.scm (5 2 1): Expose Bigloo tprint redefinition bug.
   (test-bignum): Convert test bignums from strings.
   (have-bignums?): Check bignum arithmetic works.
   (test-inexact): Do complex tests only if non-real numbers are
   supported.
   (test-inexact): Added equal? tests.
   (test-inexact): Test for -0.0 lossage.
   (test-inexact): Check that / and magnitude work for
   very large and very small complex numbers (1e300; 1e-300);
