[QBS] Patch suggestions

[Vincent Gouvernelle]

Hi,

I don't known where to give these possible patches to compile with 
MSVC-2012 and 64bits... So I give you my modification here... Maybe you 
can add it to your sources...

To compile in 64bit (for example by calling: qbs.exe release 
qbs.platform:MSVC2010 qbs.architecture:x86_64)
Modify : share/qbs/modules/cpp/msvc.js by inserting on line 150 (after 
"var is64bit = (architecture == "x86_64")")
the lines:
     if (is64bit)
         args.push('/MACHINE:X64')

To compile with msvc2012 (for example by calling qbs.exe release 
qbs.platform:MSVC2012 qbs.architecture:x86_64)
We need to add the detection of this compiler.
Modify: src/app/platforms/msvcprobe.cpp (lines marked by + are added)
150          case 10:
151              msvc.version = QLatin1String("2010");
152              break;
153 +        case 11:
154 +            msvc.version = QLatin1String("2012");
155 +            break;
156          }
157
158          if (msvc.version.isEmpty()) {
159              qstdout << "  Unknown MSVC version " << nVersion << " 
found." << endl;
160              continue;
161          }
162
163          // Check existence of various install scripts
164          const QString vcvars32bat = msvc.installPath + 
QLatin1String("/VC/bin/vcvars32.bat");
165          if (!QFileInfo(vcvars32bat).isFile())
166              continue;
167
168 +        // Check existence of various install scripts
169 +        const QString vcvarsallbat = msvc.installPath + 
QLatin1String("/VC/vcvarsall.bat");
170 +        if (!QFileInfo(vcvarsallbat).isFile())
171 +            continue;
172 +
173          msvcs += msvc;
174      }

One more thing... I'd like to add some other flags to the compiler like 
/fp:precise and maybe others, what is the best way to do it ?

Cheers,
Vincent G.
