Thank you for the new release.

When trying to build on Win32, the build is interrupted when ecl_min.exe crashes on its first invocation.

ECL 9.7.1:

* Printer:

 - Readtables have a new flag that makes them read-only. Function
       (si::readtable-lock readtable &optional new-flag)
  either reads the state of this flag (if NEW-FLAG is missing) or
  also sets it.

 - The compiler now uses cl_core to efficiently access certain lisp
  constants (standard packages, standard readtables, etc)

 - EXT:OUTPUT-FLOAT-INFINITY works now fine when *print-circle* is T.

 - WITH-STANDARD-IO-SYNTAX now also rebinds *print-pprint-dispatch*.

* Compiler:

 - When printing out data and reading it from a FASL file, the compiler now
  uses more strict settings avoiding usual interferences such as the user
  changing the readtable or the printing rules.

 - The compiler no longer enters the debugger when it finds an error in the
  code it compiles.

 - C:COMPILER-ERROR no longer derives from ERROR or SERIOUS-CONDITION.

 - Trapping of compiler conditions now works even for compiler errors.

 - Handlers of compiler errors can now call (ABORT). COMPILE-FILE will
  interrupt the compilation process, and the outputs values that signal
  the failure to terminate.

 - ECL no longer emits compiler notes when deleting unreachable code.

 - Compiler messages now show the offending form and file position.

 - DEFCONSTANT only had the expected compile-time side effects in the bytecodes
  compiler, not in the lisp->C translator.

 - New type information propagators for AREF, ASET, +, *, /, -, COS, SIN, ACOS,
  ABS. allow ECL to produce better code even without an additional
  back-propagation phase.

 - Code to perform a type inference pass, with which-way information has
  been added to ECL. The code is still in a debug phase, with lots of debug
  output printed and rather incomplete, but it is by default deactivated and
  should not interfere with usual functioning.

 - The code for inlining functions has been improved. Some safe inline
  expansions that were already available are now actively used thanks to these

 - Formerly, by historical reasons, many library functions that take a fixed
  number of arguments were declared as functions with a variable number of
  arguments. This slows down ECL and prevents detecting certain errors. In an
  ongoing effort to solve this problem, the C prototypes of COSH, SINH, CIS,
  ACOSH, ASINH and ISQRT now take only one argument (i.e. cl_cosh(cl_object x)
  instead of cl_cosh(cl_narg narg, cl_object x, ...))

* Visible changes:

 - The toplevel only traps SERIOUS-CONDITIONS.

 - "make clean" now wipes out the entire content of the build directory. Please
  use this before re-configuring again ECL so that header and configuration
  files are properly updated.
