[Ecls-list] [ANN] ECL v9.10.2

[Juan Jose Garcia-Ripoll]

When the moment of producing a release approaches, there is always the
inherent feeling that everything will go wrong. But sometimes it goes
even worse.

In this case I have been waiting several days to produce a stable
release of ECL, watching at our compiler farm and feeling very happy
about the results (http://ecls.sf.net/logs.html). What I had not
realized is that, first, our CVS repository had gotten out of sync
with the GIT repository. That is bad by itself. But second, the
testing farm had been running obsolete executables for several days.

It was quite embarrasing to get several emails complaining that ECL
did not build in Linux, OS X and other platforms. But I think I have
managed to solve most problems (see below).

The status remains as follows:

- NetBSD, OpenBSD and Mingw/Windows do not support threads unless you
use the unstable version of the Boehm-Weiser garbage collector.

- To build _any_ Windows port (including Mingw), you need now a
multithreaded environment. This means in practice that Mingw by
default is broken, unless, as I said before, you use the alpha release
of the garbage collector.

- Support for building ECL with a C++ compiler is momentarily broken.

Apart from these, all the improvements that I mention in the full
CHANGELOG remain.

ECL 9.10.2:
===========

* Bugs fixed:

 - Fixed typo in src/c/unixint.d that affected single-threaded builds

 - The GMP library did not build in OS X Snow Leopard in 64-bits mode.

 - The package MP is needed also in single-threaded versions (for fake
   mp:with-lock, which is used in CLX).

 - In CLX, there were a couple of typos in the code related to locks and ECL.
   These typos only revealed in multithreaded builds of the CLX library.

 - In Linux there is a problem with handlers for SIGFPE being totally ignored
   by the system. The problem seems to be solved by avoiding the use of
   feenableexcept() and restricting to C99 exception tests. That is bad because
   we can not reliably and cheaply detect underflow exceptions.

 - Under OS X, --enable-rpath works again. It was broken for about a year
   due to my misunderstanding of how -install_name works and the differences
   between that and -rpath.
