Fails to build with newer glibc (2.49) due to `_BSD_SOURCE` macro

starthal commented 8 years ago

When building with

./configure --target-list="aarch64-softmmu" --enable-fdt --disable-kvm

I get a warning that halts the build:

In file included from /usr/include/stdint.h:25:0,
             from /usr/lib/gcc/x86_64-linux-gnu/5/include/stdint.h:9,
             from /home/salbert/work/hzynq/zynq-vm/qemu/hw/core/remote-port-proto.c:27:
/usr/include/features.h:148:3: error: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Werror=cpp]
 # warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"

I think this has to do with compiling against a newer glibc (2.49.6-1).

Replacing _BSD_SOURCE with _DEFAULT_SOURCE in remote-port-proto.c fixes the build, but I don't know whether there are any side effects.
