This is needed on platforms like ubuntu 14.04 where several version of
clang can be installed, and the version is included in the location. The
best way is to use the llvm-config if available

Bug 738063 - Fortran attribute contiguous not identified

Empty entry in \tableofcontents in case e.g. section without description

Generate error message in case bibtex generation fails

Added keywords contiguous and volatile

In case a section, subsection etc just has a tag and not a description in the \tableofcontents there is nothing mentioned. With this patch the tag is used as description when no description is present, as is done on other places as well (consistency and no empty items in the \tableofcontents).

In case bibtex fails no message is given. When perl is missing the OS just emits an message. With this patch doxygen logs a message (analogous to other calls to portable_system)

Bug 735929 - [PATCH] Windows: Process exit code is ignored for processes launched using ShellExecuteEx()

Fix bug with C++11 static_assert

When processing a C++11 static_assert, we wish to skip the arguments. However, the `roundCount` is set to 1 despite the fact that the `SkipRound` routine will increment `roundCount` when it's entered. This causes the rest of the class to be skipped entirely.
