[Haskell-cafe] C2HS parse error on Windows ...

[aditya siram]

Hi all,
c2hs runs into the following error on all of my .chs files, but only on
Windows:
c:\\program files\\haskell
platform\\2014.2.0.0\\mingw\\bin\\../lib/gcc/x86_64-w64-mingw32/4.6.3/../../../../x86_64-w64-mingw32/include/stddef.h:20:
(column 11)
 [ERROR]  >>> Syntax error !
  The symbol `__attribute__' does not fit here.

My c2hs version is:
C->Haskell Compiler, version 0.23.1 Snowbounder, 31 Oct 2014
  build platform is "x86_64-mingw32" <1, True, True, 1>

This is the command being run:
"c:\Users\deech\AppData\Roaming\cabal\bin\c2hs.exe"
   "--cpp=c:\Program Files\Haskell Platform\2014.2.0.0\mingw\bin\gcc.exe"

   "--output-dir=dist\build"
"--output=Graphics\UI\FLTK\LowLevel\HorValueSlider.hs"
   "src\Graphics\UI\FLTK\LowLevel\HorValueSlider.chs"

A little Googling turned up this thread:
http://haskell.1045720.n5.nabble.com/BUG-string-h-FC4-x86-64-td3196369.html
which suggested I pass -D__attribute__(A)= to c2hs's opts. I tried it and
it led to other errors. I didn't pursue any further  because it's an old
thread. I'm not sure what stddef.h is and I'm unfamiliar with Windows.

Any help is appreciated.
Thanks!
