+-------------------------------------------

+CONSTANT:
+ ``CONFIGURE_MAXIMUM_THREAD_LOCAL_STORAGE_SIZE``
+
+OPTION TYPE:
+ This configuration option is an integer define.
+
+DEFAULT VALUE:
+ The default value is 0.
+
+VALUE CONSTRAINTS:
+ The value of this configuration option shall be greater than or equal to 0
+ and less than or equal to `SIZE_MAX
<https://en.cppreference.com/w/c/types/limits>`_.
+
+DESCRIPTION:
+ If the value of this configuration option is greater than zero, then it
+ defines the maximum thread-local storage size, otherwise the thread-local
+ storage size is defined by the linker depending on the thread-local storage
+ objects used by the application in the statically-linked executable.
+
+NOTES:
+ This configuration option can be used to reserve space for the dynamic
linking
+ of modules with thread-local storage objects.
+
+ If the thread-local storage size defined by the thread-local storage
+ objects used by the application in the statically-linked executable is
greater
+ than a non-zero value of this configuration option, then a fatal error will
+ occur during system initialization.
