[Bug target/45208] New: powerpc-gcc -msdata breakdown on incomplete initializers

["corsepiu at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling the code-snippet below with powerpc-*-gcc -msdata,
this error happens:

# powerpc-rtems4.11-gcc -c test.c -o test.o -msdata
test.c:10: error: rtems_filesystem_mount_table_size causes a section type
conflict

--- snip ---
int pipe (int __fildes[2] );

void Init( void )
{
  int fd[2] = {0};

  pipe( fd );
}

const int rtems_filesystem_mount_table_size = 1;
--- snip ---

This error does not happen, when
- compiling this snippet without -msdata
- expanding "int fd[2] = {0};" into "int fd[2] = {0,0};

I am able to reproduce this bug with GCC 4.2.4, 4.3.2, 4.4.4, 4.5.1,
all targetting "powerpc-rtems".
