Could you prepare a patch to Makefile.am which > p11-kit builds correctly with -D_XOPEN_SOURCE=600 or -D_XOPEN_SOURCE=500 > Thanks for doing the research. I am intentionally throwing in a great amounts of imhos, afaikss et al since I am no programmer. It is also what gnustep-base (via AC_USE_SYSTEM_EXTENSIONS) and samhain chose to do when a similar bug appeared However gnulib's threadlib.m4 is using _GNU_SOURCE. I really do not know which one is preferable. p11-kit builds correctly with -D_XOPEN_SOURCE=600 or -D_XOPEN_SOURCE=500. Which seems to legitimize kFreeBSD behavior. As far as I understand the standard an application using XSI has to set _XOPEN_SOURCE accordingly.
