[C2hs] Problems with c2hs,
including `__attribute__' symbol in _mingw.h

Regarding (3): I tried to do as was suggested in linked mail.
This first run is without the fix, clearly matrix.h is found
$ c2hs --cppopts='-I/c/Apps/MATLAB704/extern/include'
--include=C:/Apps/MATLAB704/extern/include matrix.h MxMatrix.chs
c2hs.exe: Generic fatal error.
t.h:125: (column 8) [FATAL]
>>> Syntax error!
The symbol `__attribute__' does not fit here.
This is the second run, with the appropriate defs to get rid of the problem.
Clearly the args to --cppopts are getting screwed up. I also tried with
"-I..." but got the same error.
$ c2hs --cppopts='-I/c/Apps/MATLAB704/extern/include -D__asm__(A)=
-D__attribute__(A)=' --include=C:/Apps/MATLAB704/extern/include matrix.h
MxMatrix.h:1:20: matrix.h: No such file or directory
c2hs.exe: Error during preprocessing custom header file
What am I not doing correctly?
