OFYI, I have compiled some ports I am working on and the C-compiler seems to work.
As a last check I have compiled the library sources and I got the following warning
that makes compilation stop:

gcc ... -c dosexec.c
dosexec.c: In function 'direct_exec_tail':

After disableing -Werror I have seen no other warnings that would stop the build.
