# !PATCH
# AC_FUNC_MALLOC and AC_FUNC_REALLOC test whether malloc(0) and realloc(0, 0)
# are handled like in GNU and if not, they set this "#define malloc rpl_malloc"
# and "#define realloc rpl_realloc" which stands for "replacement
# malloc/realloc".
# I can't tell if they're needed here (both because I don't know if
# MS/mingw-w64 functions behave like in GNU and because I can't tell if json-c
# requires such a behaviour. In any case, currently the replacement functions
# are not provided which indicates they're probably not needed.
# The way to avoid these defines is to remove the tests from configure.ac and
# the defines from config.h.in but in order to avoid a lengthy autoreconf, this
# only removes changes config.h.in.
