GCC 4.3.0 i386-pc-mingw32 ALPHA Release

I've uploaded a binary release of GCC 4.3.0 to the FRS.

You can get it in the usual place in the FRS as either
gcc-4.3.0-mingw-alpha-20080403.7z or gcc-4.3.0-mingw-alpha-20080403.tar.gz.

I've included a version in 7-Zip because its smaller by a huge factor.
Note there is only a single tarball, because I'd really like people to
look at the whole compiler.  The next alpha release will be split in the
usual way.

This release is intended for testing GCC, and not for general
development use.

Warning: This is an alpha release.  That means the build contains
serious problems that are likely to cause serious problems, including
silent incorrect code compilation.

Instructions:

Extract it somewhere.  Add the bin/ folder to your PATH variable.
If you extract this over your existing MinGW installation, it will
replace your current GCC version's driver executables and documentation.

This release uses about 500 megabytes of disk space when decompressed.


This is a GCC 4.3.0 tree, with the following changes

shared libgcc enabled
vtable symbol fix
main symbol fix
static object build system fix

These are mainly derived from Danny's 4.2 patchset.

All languages (Ada, C, C++, Fortran, Java, Objective-C, Objective-C++)
appear to be basically working.  The testsuite results are fairly bad,
so they may not be working very well.

Two major components are disabled : OpenMP support and mudflap pointer
checking.

This release is probably ABI incompatible with all other GCC versions
for all languages other than C.  C should be OK for portable code that
isn't compiled with exception support.

This release is compiled to support Dwarf2 exception handling only.
Dwarf2 is mutually incompatible with all other exception handling
schemes, and foreign frames.

If you want to throw exceptions between modules, you need to compile
with -shared-gcclib.
