Replace a ton of trivial #ifdefs with runtime checks

This one is big, but unless I missed something, should be all be
trivial.

scripted-diff with the following, then manually tweaked whatever needed:
```

if [ $# -ne 3 ]; then
    echo "Usage: $0 '<pattern>' '<replacement>' '<filename>'"
    exit 1
fi

pattern="$1"
replacement="$2"
filename="$3"

if [ ! -f "$filename" ]; then
    echo "Error: File $filename does not exist."
    exit 1
fi

sed -i '/'"$pattern"'/ {
    :loop
    $ !{
        N
        /'"$pattern"'.*\n.*#endif/ {
            s/'"$pattern"'/'"$replacement"'/
            s/#else/} else {/
            s/#endif/}/
            P
            D
        }
        /'"$pattern"'/ b loop
    }
}' "$filename"

echo "Replacement complete in $filename"
```
