# The KIM API code uses POSIX.1-2008 functions such as strdup() or mkstemp(), which are
# not part of the ISO C standard. Thus, when compiling with -std=c++98 instead of -std=gnu98,
# these function would be unavailable.
# Defining _DEFAULT_SOURCE during compilation tells the GNU C Library headers to make the
# POSIX and System V functions available also in strict ANSI C mode.
