Many thanks for the info, Yaakov. Accoring to the manual -std determines the language standard and c11 means ISO C11, the 2011 revision of the ISO C standard. Howevery, I find no restriction on POSIX in ISO/IEC 9899:2011. So why should -std=c11 have an influence on Pthreads? Am I missing something?
