gcc linux - 'CRTSCTS' 'ECHOCTL' undeclared (termios.h)

I am trying to compile a static library which uses serial communications on Linux, and it fails with the following errors:

gcc -o out/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/bluegiga/uart.o -c -std=gnu99 -Wall -ggdb -fPIC -Os -Wall -fPIC -pthread -m64 -DNDEBUG -DWITH_POSIX -D__linux__ -DWIFI_ADAPTER -DETHERNET_ADAPTER -DNO_EDR_ADAPTER -DNO_LE_ADAPTER -DMULTI_THREAD -D_XOPEN_SOURCE=600 -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/api -Iservice/protocol-plugin/plugins/ble/lib/api -I/usr/include/glib-2.0 -I/usr/lib/x86_64-linux-gnu/glib-2.0/include -Ideps/linux/include -Iextlibs/cereal/include -Iextlibs/cereal/cereal/include -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/inc -Iservice/protocol-plugin/plugins/ble/lib/inc -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/lib/libcoap-4.1.1 -Iservice/protocol-plugin/plugins/ble/lib/lib/libcoap-4.1.1 -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/common/inc -Iservice/protocol-plugin/plugins/ble/lib/common/inc -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/bluegiga/common/inc -Iservice/protocol-plugin/plugins/ble/lib/bluegiga/common/inc -Iresource -Iresource/include -Iresource/oc_logger/include -Iresource/csdk/stack/include -Iresource/csdk/ocrandom/include -Iresource/csdk/logger/include -Iout/linux/x86_64/release/service/protocol-plugin/plugins/ble/lib/bluegiga -Iservice/protocol-plugin/plugins/ble/lib/bluegiga service/protocol-plugin/plugins/ble/lib/bluegiga/uart.c

I've searched around for this issue, and the only information I could find was here: CRTSCTS not define when compiling as C99

Unfortunately, the solution (using -std=gnu99) didn't work for me.

Here is some environment information:

$ gcc --version
$ gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2

$ uname -r
$ 3.13.0-48-generic

The problem was the -D_XOPEN_SOURCE=600 part of the gcc command. After removing it, everything compiled without problems.

The more detailed explanation can be found in the answer to the question I linked to.
