|
|
* This file has several purposes.
|
|
*
|
|
* - Its purpose is the same as that of x86_64-linux-gnu/sys/cdefs.h, that is,
|
|
* it defines things that are dependent upon the compilation environment.
|
|
* - Since this *must* be included as the very first header by all other MaxScale
|
|
* headers, it allows you to redefine things globally, should that be necessary,
|
|
* for instance, when debugging something.
|
|
* - Global constants applicable across the line can be defined here.
