A new PortAudio stable release has been made.
The mxe-specific patches in src/portaudio-1-win32.patch have changed as
follows:
[Unchanged] pa_win_ds.c needs a definition for DSSPEAKER_7POINT1
from the DirectSound headers. Mingw doesn't include this constant so
we patch it.
[Added] CalculateBufferSettings() mixes int and unsigned long types.
gcc treats this sloppy use of types as an error. Manually cast since
we know it's safe on Windows where the LLP64 data model is used.
[Added] configure.in mistakingly lists pa_win_wdmks_util.o instead of
the correct filename, pa_win_wdmks_utils.o. I have sent a patch
upstream to PortAudio and we'll be able to drop this in the next
update.
[Dropped] pa_win_wdmks.c now uses special headers for mingw so we do
not need to define _WAVEFORMATEXTENSIBLE_ anymore.
[Dropped] configure.in now supports building multiple hostapis with
mingw since my patch was merged upstream in PortAudio. We no longer
need to modify LIBS.

This patch updates PortAudio to v19 20111121 from 20071207.
The src/portaudio-1-win32.patch ./configure hunks have been submitted upstream
and will be in the next PortAudio release. In the meantime we must carry this
patch to build multiple audio host APIs for Windows.
This patch also enables the WASAPI, WDM Kernel Streaming, and WinMME host APIs
for a broader selection of Windows audio APIs. WASAPI and WDM Kernel Streaming
are especially useful for low-latency audio.
