Summary 0000747: Confusing erroneous text about address-of-array in pthread_once rationale
Description The rationale text for pthread_once contains:

"Note that a pthread_once_t cannot be an array because some compilers do not accept the construct &<array_name>."

Presumably this is cruft from an ancient version of the Threads standard that was not aligned with ISO C.

Not only is the remark false for all conforming C compilers; it is confusing/misleading to have such text that seems to impose normative requirements ("cannot be") in a non-normative section. Moreover, even if ISO C did permit compilers to reject this construct, the need to avoid defining pthread_once_t with array type would apply only to implementations making use of such compilers, not to all implementations.
Desired Action Remove the text:

"Note that a pthread_once_t cannot be an array because some compilers do not accept the construct &<array_name>."

from the rationale for pthread_once.
