  I have just uploaded an updated GCC-4 package to cygwin.com.  It will be
arriving at your favourite mirror next time it synchronizes itself with the
official Cygwin repository.

  This is a stable release of GCC 4.5.3 which replaces the earlier experimental
release of GCC 4.5.0.


    ------------------------------ooOOOoo------------------------------
    PLEASE SEND BUG REPORTS, PROBLEMS, ETC. TO THE CYGWIN MAILING LIST.
    ------------------------------ooOOOoo------------------------------


OBTAINING THE RELEASE
=====================

To update your installation, click on the "Install Cygwin now" link on the
http://cygwin.com/ web page. This downloads setup.exe to your system. Then,
run setup.exe, fill in all of the options, and make appropriate choices on the
"Select Packages" screen. Because this is a full "current" version release,
any gcc packages you currently have installed will be automatically selected
to update, but you'll need to select the Devel category to see gcc and friends
if you don't have them already installed.

NEWS

> > From the README:

gcc4-4.5.3-2
- ------------------------------------------

This is the first full stable production release from the GCC 4.5 compiler
series for Cygwin, which replaces the experimental 4.5.0-1 release.  All
the major runtime libraries are implemented as DLLs as well as static
archives.  It can fully co-exist side-by-side with the older Cygwin gcc-3.4.4
series compiler.  All languages are supported, although Ada and Java remain
works-in-progress.


What happened to gcc4-4.5.3-1?
==============================

This release number was used for the initial cygwinports version of the
gcc4-4.5.3 packages.  Skipping it in the main release series avoids any
problems for cygwinports users.

Known issues in Ada and Java.
=============================

The Ada compiler is currently implemented as a Frankenstein-like hybrid of
Cygwin/POSIX and MinGw/w32api code.  This just barely hangs together, but
does not play nicely with Cygwin's pthread library functions; the outcome
is problems in the tasking implementation, including race conditions that
may lead to failure in early startup or termination.

There are problems with the Java compiler that are less well understood,
but also manifest themselves as testsuite failures in the thread- and
process-related tests.

These issues will be addressed in a future release of the compiler; for
now, Java and Ada cannot be considered first-class languages, but remain
somewhat experimental.  It is likely however that both perform better than
the old 3.4 series compilers.
