configure failed for lib-src/portmixer

Benjamin Drung gets this problem on Ubuntu 10.10 and says there is no
system port audio version nor other portmixer headers installed.

Richard thinks it's an Audacity problem which only shows up with very recent toolchains (maybe GCC-version sensitive). The problem has been reported as a Gentoo bug as well. The speculation there was that some change in recent GCC had broken one of the autoconf macros we use in the portmixer configure script 
(AC_EGREP_HEADERS?).

We have found the reason for the failing AC_EGREP_HEADER: gcc 4.5
changed the behavior: If a header named in a #include directive is not
found, the compiler exits immediately. This avoids a cascade of errors
arising from declarations expected to be found in that header being
missing.

The configure script checks the existence of
PaMacCore_GetStreamInputDevice in pa_mac_core.h, which is used in
src/px_mac_coreaudio.c. Afterwards it checks if src/px_mac_coreaudio.c
should be built.

On Ubuntu, we don't want to build src/px_mac_coreaudio.c and we don't
have the required AudioUnit/AudioUnit.h header, which leads to this bug.

The fix (suggested by Matthias) is to only run the AC_EGREP_HEADER test,
if you build src/px_mac_coreaudio.c. This means to change the order of
AC_CHECK_HEADERS and AC_EGREP_HEADER in configure.ac.

configure.ac.patch

Here is my patch for switching the order. After applying the patch you
have to run autoreconf in lib-src/portmixer.

anyone has any other input I think we can just move it to "RESOLVED -

autoreconf.patch

One thing is missing. The configure files needs to be regenerated by
running autoreconf. You can use the attached patch if you don't have
autoreconf installed on your system. I wrote that to the mailing list
two days ago, but I don't find the mail in the archive [1].

Benjamin, can we resolve this fixed or do you want to retest (which you
can't do due to the portaudio build problem:
