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

[Vivian McPhail]

Hi,

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.

C:/Apps/MSYS/1.0/mingw/bin/../lib/gcc/mingw32/3.4.2/../../../../include/floa
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.chs
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?
