wine users - May 2012 - wineasio compile problems on OSX - COM work arounds

I dont know if this is the right place to post this question.  I've tried
already on the wineasio sourceforge forum, but no response.  I think this
particular question is something wine experts would know about since it looks to
be borrowed code from wine.  Most of the wineasio folks seem to be linux focused
only.

In any case, I'm trying to compile the latest wineasio 0.90 on OSX 10.6.8. 
I have already built wine 1.5.4.

I get some errors immediately related to some ELF assembler code injection that
I believe has to do with working around COM.  Here is the error and below that
is the code I think causing the problem to build.  Does anyone have any ideas
what I would need to tweak to get past this particular problem?


Code:
gcc -c -I. -I/usr/include -I/Users/sjs/wine/wine-1.5.4/include
-I/Users/sjs/wine/wine-1.5.4/include/wine
-I/Users/sjs/wine/wine-1.5.4/include/wine/windows    -m32 -g -O2 -D__WINESRC__
-D_REENTRANT -fPIC -Wall -pipe -fno-strict-aliasing
-Wdeclaration-after-statement -Wwrite-strings -Wpointer-arith -o asio.o asio.c
{standard input}:36:Unknown pseudo-op: .type
{standard input}:36:Rest of line ignored. 1st junk character valued 95 (_).
{standard input}:38:Unknown pseudo-op: .cfi_startproc
{standard input}:43:Unknown pseudo-op: .cfi_endproc
{standard input}:44:Unknown pseudo-op: .previous
{standard input}:48:Unknown pseudo-op: .type




I'm pretty sure this is the code causing the problem.


Code:
/* ASIO drivers (breaking the COM specification) use the Microsoft variety of
 * thiscall calling convention which gcc is unable to produce.  These macros
 * add an extra layer to fixup the registers. Borrowed from config.h and the
 * wine source code.

Wineasio is a separate project; it is not supported here.

apparantly its not supported anywhere

Why are you trying to use this?  Mac sound support is through coreaudio.

James

wine does not produce low latency audio through coreaudio.  Perhaps you can tell
me something I don't know about, but everyone I know using wine with audio
production apps has to use wineasio in order to get low latency audio out of
reaper, etc.   If you know another way to try, please advise and I will gladly
try it.  However, to my knowledge, wineasio is the only way.

the COM work around code above was borrowed from wine, so I hope someone
knowledgable about it can show how to make it compile on osx.  thanks
