Subject: [PATCH] src/libuwac/uwac-os.c: fix build with uclibc
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

O_TMPFILE is used since version 2.0.0 and
https://github.com/FreeRDP/FreeRDP/commit/52ef8079eae74dfe89e6779c873101843b8cc42b

However, this will result in the following build failure on uclibc or
uclibc-ng:

/home/fabrice/buildroot/output/build/freerdp-2.0.0/uwac/libuwac/uwac-os.c:228:18: error: ‘O_TMPFILE’ undeclared (first use in this function); did you mean ‘EMFILE’?
  fd = open(path, O_TMPFILE | O_RDWR | O_EXCL, 0600);
                  ^~~~~~~~~
                  EMFILE

To fix this build failure, define O_TMPFILE if needed
