Message:

Runtime/r0drv/solaris/semeventwait: Silence a Solaris-specific spurious
gcc -Wmaybe-uninitialized warning in rtR0SemSolWaitDoIt(). gcc 13.1
emits: "warning: ‘u.idCo’ may be used uninitialized [-Wmaybe-uninitialized]:
413 | untimeout(u.idTom);". The gcc manpage explains that its uninitialized
variable usage analysis is indeterminate and hence uses 'maybe': "the
compiler emits a warning if it cannot prove the uninitialized paths are
not executed at run time". In this case the code is fine as-is and thus
this is a false positive but we initialize 'u.idCo' anyways to silence gcc.
