* Use -std=c++11 flag for gcc and clang
* Use $$PWD variable in qmake files to have correct paths
* Change tokenizer.simplifyTokenList() to tokenizer.simplifyTokenList2()
* Add build-generated files to .gitignore
* Link libpcre only if rules are enabled
Neither the C standard, the C++ standard, or POSIX talks about "obsolete". All of them use the word "obsolescent", which is a different word with a different meaning.
- fix g++ warning:
> lib/checkother.cpp:3779: warning: comparison between signed and unsigned integer expressions
- fix suncc warning (see [everything2](http://everything2.com/title/C%252B%252B%253A+static+extern+%2522C%2522)):
> "lib/checkmemoryleak.cpp", line 578: Warning (Anachronism): Formal argument __compar of type extern "C" int(*)(const void*,const void*) in call to bsearch(const void*, const void*, unsigned long, unsigned long, extern "C" int(*)(const void*,const void*)) is being passed int(*)(const void*,const void*).
- prefer empty() / isEmpty() over "size() > 0" (cases not caught by stlSize)
- fix word misspellings (mostly comments, a few output lines)
- Parenthesis => Parentheses (both variations were used in the codebase)
- fix typo and wording ("never alwayw") in gui/test/data/benchmark/simple.cpp's CheckOther::unsignedPositive():
```
- "An unsigned variable will never alwayw be positive so it is either pointless or "
+ "An unsigned variable can't be negative so it is either pointless or "
```
The benchmark data file had errors when checking with Cppcheck.
And people reported these errors. So replace the file with one
that has no (currently found) errors.
The script is available in another repository. I don't want to
distribute it with Cppcheck sources for now. Maybe if and when
there is more interest towards GUI tests...
