/* NuttX prefers defining limits per architecture directly as constants
|

|

* instead of using compiler provided definitions. That is to support
|
||
|
|
* compilers that do not provide such definitions. On the other hand in case
|
||
|
|
* compiler provides these definitions we should not deviate from them. This
|

* file thus contains only checks of NuttX's defined limits against compiler
|
