[Portaudio] configure.in patch (was: Re: ASIO/MinGW install)

Tue Dec 8 04:40:39 EST 2009

Hi All

I have now checked in the autoconf changes from Stelios Bounanos (see the 
two emails copied below). I have not tested this myself.
>>>>
Update to Makefile.in and Configure.in from Stelios Bounanos: Pretty-print 
help strings, Support multiple APIs on win32 with mingw, Output a 
configuration summary at the end, Remove ASIO build configuration from OSX
<<<<

I think someone still needs to regenerate the actual configure script (?) 
since Stelios wrote:

> autoconf,

Could people please test this and send me a copy of the generated files when 
you're happy? thanks.

Thanks

Ross.
