// This hack is needed to get around an odd and hard-to-reproduce problem
// with HP aC++. If struct sigaction is defined extern "C" and the sigaction
// function in namespace ACE_OS, the compiler sometimes gets confused.
// If we help it with this typedef, it's fine. User code should not use
// the ACE typedef - it will be removed without warning as soon as we can
// either drop support for the broken compilers or figure out how to reproduce
// it so it can be reported to HP and fixed.
// There's a similar hack in OS_TLI.h for struct t_optmgmt.
