* up to 4.8; GCC >= 4.9 can include unconditionally
* - Clang: same as GCC, with unconditional inclusion with version 3.7
* - Intel CC: #include can happen unconditionally
* - MSVC: #include can happen unconditionally
* - RVCT: ???
*
* We will try to include all headers possible under this configuration.
