    net-misc/vncrec: force gcc -E for imake's generation
    Requires traditional cpp support and is broken in all sort of ways
    with clang-cpp / -E. Can still use clang & friends for everything else.
    Ideally these packages need to be built another way or last rited,
    imake will just accumulate more problems.

    net-misc/vncrec: further fix w/ upcoming clang16
    When last tested this package, did not know clang16 was newly enabling
    -Werror=incompatible-pointer-types yet and hadn't looked at this.
    Bit dodgy here given we don't know what the X11 headers want, i.e.
    _X_NORETURN could be set or not set, and an update could remove it
    from XtErrorhandler entirely (so passing it may break later) -- so
    pass -Wno-error instead (should be harmless in this case).
