[Sdcc-user] New sdcc snaphot build plarform: 64 bit Windows

[Borut R. <bor...@gm...>]

Hi sdcc users and developers,

if you carefully looked to the SDCC Snapshot Build web page, you might 
noticed two new items: "Windows 64bit (experimental) 
(x86_64-w64-mingw32)" and "Windows 64bit package with installer 
(experimental) (x86_64-w64-mingw32-setup)".

Both contains the native 64 bit Windows compiled sdcc suite. The builds 
are done on Erik's cf-x86 amd64 Fedora 12 Linux machine, cross-compiled 
in mingw_w64 environment (libraries, header files, ...) with 
x86_64-w64-mingw32-gcc (GCC) 4.5.4 (prerelease). Regression test are ran 
on the same machine with wine64 and they all pass.

The zip packages sdcc-snapshot-x86_64-w64-mingw32-yyyymmdd-bbbb.zip are 
quite complete. The only remaining TODO is compilation of 64 bit 
readline5.dll and it's inclusion.

The setup package still needs some work:

    * I just noticed that it has to be renamed since the name is same as
      for 32 bit packages. The new name will probably be
      sdcc-yyyymmdd-bbbb-w64-setup.exe
    * Detection when trying yo install 64 bit package on 32 bit Windows
    * Proper installation in 64 bit registry and in 64 bit "Program
      Files". Currently it is incorrectly installed as 32 bit
      application in "Program Files (x86)" directory.
    * Already mentioned inclusion of 64 bit readline5.dll

Any reports of successful or unsuccessful installation & execution are 
welcome!

Thanks to Erik Petrich to upgrade cf-x86 to Fedora 12 (glibc 2.11 is 
required by brebuild mingw_w64)  and to gcc, mingw_w64 and wine teams to 
make this possible.
