I sent offlist a couple of times but notice that the latest patch is missing
this bit around AC_CHECK_HEADERS, which apparently can sometimes cause
warnings on mac.
ac_save_CPPFLAGS=$CPPFLAGS
CPPFLAGS="$LZ4_CFLAGS $CPPFLAGS"
AC_CHECK_HEADERS(lz4/lz4.h, [],
[AC_CHECK_HEADERS(lz4.h, [], [AC_MSG_ERROR([lz4.h header file is required
for LZ4])])])
CPPFLAGS=$ac_save_CPPFLAGS
