To fix that, I must define _USE_XOPEN
You really, really must not use this macro.
I'm glad to hear something definitive about that. I don't even remember
how I arrived at that hack.
FYI
/usr/include/sys/features.h
provides the full framework for the different options
Define both to allow everything:
_DEFAULT_SOURCE enables BSD and SysV features, is the default if *NO* others
defined, and replaces old _BSD_SOURCE and/or _SVID_SOURCE
_GNU_SOURCE enables all the GNU, X/Open, POSIX, C, etc. features but original
Unix SysV and BSD extensions
Search online for man 7 feature_test_macros, copy from a Linux system, or
download, and install the man page under /usr/local/man/man7/ for reference.
