--- Comment #31 from joseph at codesourcery dot com <joseph at codesourcery dot com> --- The following targets still appear to be missing this type information in GCC: some NetBSD targets (netbsd-stdint.h only used for x86 / x86_64), VxWorks, SymbianOS, LynxOS, QNX, TPF. Others have either been fixed, or obsoleted and removed.
