Problems with building a mingw cross-compiler

[Paul Millar <paulm at astro dot gla dot ac dot uk>]

Hi,

I'm trying to compile a cross-compiler that will generate Windows binaries 
from a Linux host.  I'm hitting two (probably related) problems.

The first problem is that gcc/crtstuff.c includes
gcc/config/i386/cygming.h, which tries to #include <stdio.h>, but fails.  
This leads to FILE not being defined, causing prototypes to fail:

Changing gcc/config/i386/cygming.h via:

-#include <stdio.h>
+#include "system.h"
 #include "i386/gas.h"
 #include "dbxcoff.h"
 
allows the compilation to continue.

However, later the compilation fails again.  This time, gcc complains
about missing header files, and that malloc is poisoned (whatever *that*
means).

I'm using gcc-3.2.1 (from http://www.trilithium.com/software/misc/) to
compile gcc-3.2.1 for the target i386-mingw32.  I've tried various
configurations (and variations on the target), none have worked.  For the
above compilation, I used:

  ../configure --target=i386-mingw32 --prefix=/usr/local 
  --with-local-prefix=/usr/local/i386-mingw32 --with-newlib 
  --enable-threads --disable-nls --enable-languages=c,c++,f77,objc 
  --disable-win32-registry --disable-shared --enable-sjlj-exceptions


This looks like some kind of path problem (cause by configure?). If so,
I'm not sure what's gone wrong.  The directory /usr/local/i386-mingw32
doesn't exist yet.

I've placed the config.cache file at:
   http://www.astro.gla.ac.uk/users/paulm/config.cache
in case its of any use.

I've also tried gcc-3.2 as well, with (more or less) identical results.

Any ideas?

Cheers,

Paul.

PS.
[path] above is /usr/src/redhat/BUILD/gcc-3..2.1-20021201-2 btw.
