st_birthtime is a BSD-specific extension to the stat structure.

Somehow CMake detects that st_birthtime is present in sys/stat.h but
then the compilation fails because that field cannot be found.

So my guess is that the check in CMake is not working correctly.

WEBKIT_CHECK_HAVE_STRUCT(HAVE_STAT_BIRTHTIME "struct stat" st_birthtime sys/stat.h)

Can you tell us the version of the operating system, C++ compiler, C
library and CMake that you are using to build WebKitGTK?
