If POSIX 2008 and/or C99 do not mandate static_assert, it must be hidden for them. A general rule is that system headers cannot pollute name spaces of t= he user when directed to do so by things like POSIX_C_SOURCE. static_assert was added, I believe, in C11 and C++11. As such, it should be hidden from the 2008 posix environment. I've not checked to see if there's a newer value of POSIX_C_SOURCE that sho= uld define a higher value of either __POSIX_VISIBLE or __ISO_C_VISIBLE, but sin= ce you're using 200809, that's not relevant. --=20 You are receiving this mail because: You are the assignee for the bug.=
