Comment 20 for bug 1123588

Scott is right - the description of this attribute *has* changed. Compare the current description to:

http://web.archive.org/web/20060824111504/http://gcc.gnu.org/onlinedocs/gcc/Function-Attributes.html

Hence, either the attribute used to be incorrectly described and we were just lucky not to see any issues until now, or the meaning of this attribute has been changed by the gcc folk since it was introduced.
