    c++: fix error reporting routines re-entered ICE [PR110175]

    Here we get the "error reporting routines re-entered" ICE because
    of an unguarded use of warning_at.  While at it, I added a check
    for a warning_at just above it.

            * typeck.cc (cp_build_unary_op): Check tf_warning before warnin=
g.
