[Development] Qt5 release integration build

[Kurt Pattyn]

Hi,

is anybody aware of the many warnings of Qt5 release build for Windows?
For instance the build win32-msvc2010_developer-build_qtnamespace_Windows_7 (build log: http://testresults.qt-project.org/ci/Qt5_release_Integration/build_00286/win32-msvc2010_developer-build_qtnamespace_Windows_7/log.txt.gz), contains the following warnings:

warning C4996: 'fopen': This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
warning C4996: 'strncpy': This function or variable may be unsafe. Consider using strncpy_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
warning C4996: 'strerror': This function or variable may be unsafe. Consider using strerror_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.
And a lot more of these ‘unsafe’ warnings, probably harmless.
I think the following ones needs more attention:
warning C4018: '>' : signed/unsigned mismatch
warning C4146: unary minus operator applied to unsigned type, result still unsigned
warning C4305: 'argument' : truncation from 'double' to 'float'
warning C4138: '*/' found outside of comment
Command line warning D9025 : overriding '/Zm200' with '/Zm500'
warning C4996: 'putenv': The POSIX name for this item is deprecated. Instead, use the ISO C++ conformant name: _putenv. See online help for details.
warning C4189: 'eventDispatcher' : local variable is initialized but not referenced
testqrc\test.qrc: Warning: potential duplicate alias detected: 'aliasdir.txt'
warning C4341: 'EnumTest_Enum1_bigValue' : signed value is out of range for enum constant
warning C4309: 'initializing' : truncation of constant value
warning C4290: C++ exception specification ignored except to indicate a function is not __declspec(nothrow)
warning C4996: 'FunctionWithAttributes::test2': was declared deprecated
warning C4723: potential divide by 0
warning C4005: 'M_E' : macro redefinition
warning C4530: C++ exception handler used, but unwind semantics are not enabled. Specify /EHsc
warning C4307: '*' : integral constant overflow
warning D9002 : ignoring unknown option '-g'
warning C4995: 'UnknownBaud': name was marked as #pragma deprecated
warning C4244: 'function' : conversion from 'uint64' to 'size_t', possible loss of data
warning C4345: behavior change: an object of POD type constructed with an initializer of the form () will be default-initialized
Cheers,

Kurt
