This doesn't turn on the kernel POSIX support.  cc -Xp or OSTYPE=POSIX cc
or cc /lib/lcrtp.o or doing the system call that the latter does will.

>i never tried the stuff mentioned in cc(1) like setenv OSTYPE POSIX,

That is interpreted by cc, not gcc.  It is equivalent to the -Xp flag and
causes linking with /lib/crtp1.o and /lib/libcposix.a .

>never ever have i seen a panic whatsoever.

Because you aren't using kernel posix.
