scm-5f2 news:

scm-5f2 improves the speed of floating-point I/O.  Details at
<http://cvs.savannah.gnu.org/viewvc/*checkout*/scm/scm/ChangeLog>

  * scl.c (int2dbl, pmantexp2dbl): Recycle temporary bignums.
  (pmantexp2dbl): Handle exponents smaller than -324.
  (pmantexp2dbl): Optimized.  Added bigrecy(quo).
  (pmantexp2dbl): call int2dbl() instead of num2dbl().
  (pdbl2str, pmantexp2dbl): Use powers-of-5 table instead of powers-of-10.
  (strrecy, pdbl2str): Recycle temporary string used in number->string
  conversion.
  (scm_intexpt): Call bigrecy only when #ifdef BIGDIG.
  (bigrecy): Added procedure to recycle bignums.
  (int2dbl, scm_intexpt, divide, difference, big2str)
  (pdbl2str, mantexp2dbl, pmantexp2dbl, int2dbl): Recycle temporary bignums.
  (pdbl2str): Replaced call to int2dbl() with scm_intlength().
  * r4rstest.scm (test-bignum): Added tests for GCD and LCM.
  * sys.c (sysptob): Added sysflush (for sys_errp).  Fixed exit when
  verbose > 3.
  * subr.c (scm_bitwise_bit_count, scm_logcount, scm_intlength)
  (big2inum): Recycle temporary bignums.
  * scm.c (process_signals): Reenabled lfflush(sys_errp).
  * scm.texi: TeXinfo-5 now disallows text between @defunx lines.
  (Internal State): Added "(gc #t)".

From: Marc Espie

  * time.c: OpenBSD is phasing out old interfaces such as ftime and
  the timeb data structure.  This change should allow things to work
  in a saner way on any system that uses gettimeofday().
