[Mingw-w64-public] TDM-GCC 4.5.1 released

[John E. / T. <td...@td...>]

  Greetings!

*TDM-GCC 4.5.1 is now available!*

* With the 4.5.1 release, GCC now includes support for LTO on MinGW and 
MinGW-w64 targets, so it's enabled in TDM-GCC.
* As with the 4.5.0 release, I've maintained the *reversal* of the GCC 
change that caused an out-of-memory problem building wxWidgets due to 
the forced emission of class inline functions in DLL code. This means 
that you shouldn't have to perform any unusual steps when building 
wxWidgets.

***WARNING!***
In the TDM64 edition, a widespread change has been introduced that 
affects compatibility with previous versions. In summary, for the 
x86_64-w64-mingw32 target, symbol names _*WILL NOT*_, by default, have 
an additional underscore affixed, as was previously the case for this 
target (and remains the case for 32-bit targets). This was done for 
better compatibility with Microsoft's compiler.
*This means that you must recompile all code that was compiled with an 
older TDM64 edition!*
If you fail to recompile any part of a self-contained module, or 
inadvertently mix code compiled by an older edition with code compiled 
by a newer edition, you _will_ encounter undefined symbol errors. 
Consider yourself warned.

(If you truly must, you can revert to the previous underscoring rule 
with the "-fleading-underscore" command-line option -- but don't do this 
unless you really know what you're doing.)

*TDM-GCC is available in TWO editions:*
Along with the classic MinGW 32-bit edition, a new *TDM64* edition is 
also available. This edition is based on the MinGW-w64 runtime API and 
the x86_64-w64-mingw32 GCC target, and can create both 32-bit and 64-bit 
code, with the "-m32"/"-m64" compiler flags. Please never mix 32-bit 
object files (.o), libraries (.a), DLLs or EXEs with 64-bit versions, 
and don't report it as a bug if you inadvertently do.

Alongside the GCC 4.5.1 packages are binary packages of the MinGW-w64 
runtime (based on SVN r3427), binutils (CVS as of 2010-08-16), and gdb 
(7.1).

More information and downloads are available at 
<http://tdm-gcc.tdragon.net/>. TDM-GCC includes support for C, C++, 
Fortran, Objective-C/C++, and Ada (MinGW edition only), as well as 
support for LTO and the OpenMP multithreading extensions, packaged in a 
simple Windows installer.

Cheers,
