Platform.h is intended to contain definitions and workarounds for concepts that depend upon the used compiler and/or platform. Currently it ensures that /thread_local/ is available irrespective of whether the source is compiled in pre- or post C11 or C++11 mode. This file should be included first by all MaxScale headers.
