collision.
Product: gcc
Version: 4.6.0
Status: UNCONFIRMED
Severity: normal
Priority: P3

Replace pointer_t with pointer_type in module.c to allow bootstrap on MachOS.
On powerpc-apple-darwin7.9.0 I geth the following failure on bootstrap at
stage2:

../../gcc/gcc/fortran/module.c:110:1: error: redefinition of typedef
'pointer_t' with different type
/usr/include/mach/vm_types.h:35:26: note: previous declaration of 'pointer_t'
was here
In gcc/fortran/module.c:
typedef enum
{
P_UNKNOWN = 0, P_OTHER, P_NAMESPACE, P_COMPONENT, P_SYMBOL
}
pointer_t;
In /usr/include/mach/vm_types.h:
typedef vm_offset_t pointer_t;
Interwebs search on "gfortran error: redefinition of typedef 'pointer_t' with
different type"
Got be to a macports bug tracker where:
"solved replacing all pointer_t in module.c"
The macports people note failure of previous versions too:
"Installation of gcc45 (also gcc43 and gcc44) fails:"
I am attaching an obvious patch for mainline.
Thanks,
