+Subject: [PATCH] Fix building against the system portaudio library
+
+Building against the system portaudio results in this error:
+
+./src/AudioIO.cpp:983: undefined reference to `PaUtil_GetTime'
+audacity-AudioIO.o: In function `audacityAudioCallback(void const*, void*,
+unsigned long, PaStreamCallbackTimeInfo const*, unsigned long, void*)':
+./src/AudioIO.cpp:4630: undefined reference to `PaUtil_GetTime'
+collect2: error: ld returned 1 exit status
+Makefile:2349: recipe for target 'audacity' failed
+make[3]: *** [audacity] Error 1
+
+This is because PaUtil_GetTime is declared as a C symbol in pa_util.h
+but is resolved as a C++ symbol at link time.
+
+Audacity fixes this in the local tree with this change:
+https://github.com/audacity/audacity/commit/38fd97b8e26060332ab3e9e000a8882326a70ba7
+
+However this is not general enough for the portaudio debian package.
+
+Since PaUtil_GetTime() is the only function causing problems, just copy
+over the code where it's used.
