Try this, should build fine and avoids the duplicated nousystem line.

You can do so, but I did it the way I did it
to maintain a consistent style. style(9) says
that style should only be changed for major
re-writes.

But choose whichever way you prefer.

Accepted subject to the changes I have proposed.

lib/libc/gen/strtofflags.c

It's not really a style change. More of a simplification of lines that'll be touched anyway.

[ziaee]

so like this?

[fuz]

Looks good!
