	Variable block memory pools should be statically
	initialized: enter a list of initializers
	separated by commas, one per line.
	An initializer is
	'CYG_UIT_MEMPOOLVAR(ADDR,SIZE)'
	where addr is the address of memory to manage, and
	size is the total size of that memory.
	If create and delete operations are supported,
	initializers of the form
	'CYG_UIT_MEMPOOLVAR_NOEXS(ADDR,SIZE)' should be
	used for pools which are not initially created, to tell
	the system what memory to use for each pool.
	Note: this option is invoked in the context of a
	C++ array initializer, between curly brackets.
	Ensure that the number of initializers here exactly
	matches the total number of variable pools specified."
