When compiling xfstests with either gcc 6.4.1 or 7.2.1 I see the following warning: In file included from /usr/include/stdio.h:27:0, from fssum.c:25: /usr/include/features.h:148:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp] # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" ^~~~~~~ The feature_test_macros(7) man page says this about _BSD_SOURCE: Since glibc 2.20, this macro is deprecated. It now has the same effect as defining _DEFAULT_SOURCE, but generates a compile-time warning (unless _DEFAULT_SOURCE is also defined). Use _DEFAULT_SOURCE instead. To allow code that requires _BSD_SOURCE in glibc 2.19 and earlier and _DEFAULT_SOURCE in glibc 2.20 and later to compile without warnings, define both _BSD_SOURCE and _DEFAULT_SOURCE. Keep backwards compatibility with older code by defining both _BSD_SOURCE and _DEFAULT_SOURCE.
