Ooops... Sorry. Copied configuration from a different computer.

Tried with flag-noipv6:
        exec ./compile iobufferk_fill.c
        iobufferk_fill.c: In function 'iobufferk_tee':
        iobufferk_fill.c:14:3: warning: implicit declaration of function 'tee'

I remembered I had edited netinet/in.h, so I tried again:
        enum {
        #define IPV6_V6ONLY IPV6_V6ONLY
Same error message...

Even if it compiled, I'm having doubts about using dietlibc for this.
The problem is that dietlibc ignores right timezones, so maybe software
that uses right timezones would be silently broken?

I have musl installed, and I used it to statically compile bash (to put in
my initramfs_cum_emergency_system...)

Not working:

exec ./compile tryclockrt.c
tryclockrt.c: In function 'main':
tryclockrt.c:8:19: error: storage size of 'ts' isn't known

conf-cc: /opt/bin/musl-gcc -static -Os -march=native -mfpmath=sse -mssse3 -W -Wall -fomit-frame-pointer -pipe
conf-ld: /opt/bin/musl-gcc -static

Maybe the latter is wrong?

This one would be sort of a show-stopper for us amateur folks... (I
actually have a use for s6-devd :))

Anyway, I wanted to make sure I had the latest versions before
reporting this bug:

        #!/command/execlineb -P
        pipeline { echo blah }

The syntax error is not detected and it segfaults.
