Build errors - target i386-pc-mingw32

[Casper Hornstrup <chorns at users dot sourceforge dot net>]

Hi all.

I've been trying to compile a cross compiler (mingw) on linux and run into 
problems.

Please tell me if I doing this wrong.

I configure binutils (current cvs version) with:
configure --prefix=/usr/local/cross-tools --target=i386-pc-mingw32 -v

I put the cross compiler in the path with:
export PATH="$PATH:/usr/local/cross-tools/bin"


I copy mingw runtime include files:
cp -R mingw-runtime/include /usr/local/cross-tools/i386-mingw32/include


I configure gcc (current cvs version) with:
configure --prefix=/usr/local/cross-tools --target=i386-pc-mingw32 -v


NOTE: I use optabs.c revision 1.110 due to a bug in revision 1.111 as 
previously noted on this list.


The error I get when doing "make", is the following:

Line 172 is like this:
__MINGW_IMPORT FILE _iob[];	/* An array of FILE imported from DLL. */

And __MINGW_IMPORT is defined:
...
# ifdef __declspec
   /* note the extern at the end. This is needed to work around GCC's
      limitations in handling dllimport attribute.  */
#  define __MINGW_IMPORT __attribute__((dllimport)) extern
#  define __DECLSPEC_SUPPORTED
...

Now, just to see what would happen, I changed

# ifdef __declspec
to
# ifndef __declspec

and the build process would go further, but then I got another error:
