ImageMagick & MinGW/GCC TDM: Building Trouble (Stage 4)

With

Log.c

747:#if defined(MAGICKCORE_HAVE_PTHREAD)
748:  return( (unsigned long ) ((void *)pthread_self()));
749:#endif


and

747:#if defined(MAGICKCORE_HAVE_PTHREAD)
748:  return( *(unsigned long *) pthread_self());
749:#endif

I get (After modification (Inmediately) without make clean)

$ make
make  all-am
make[1]: Entering directory `/home/Administrador/ImageMagick-6.4.4/builds'
/bin/sh ./libtool --silent --tag=CC   --mode=compile gcc -std=gnu99
