You're going to have to explain to me how this is not a bug in FSF gcc.  The SPU language 
extensions document ( 
http://www-306.ibm.com/chips/techlib/techlib.nsf/techdocs/30B3520C93F437AB87257060006FFE5E/$file/SPU_language_extensions_2.1.pdf 
) clearly requires this to be defined.  And if we are going to start using FSF gcc to 
compile things then it follows that it is going to have to support those language 
extensions sooner rather than later.

1. Data Types and Program Directives
     This chapter describes the basic data types, operations on these data types, and 
directives and program controls
     required by this specification.
1.1. Data Types
     The SPU programming model introduces a set of fundamental vector data types to the C 
language. The vector data
     types are all 128-bit long and contain from 2 to 16 elements, depending on the data 
type. Table 1-1 shows the
     supported vector types.
     Table 1-1: Vector Data Types
             Vector Data Type                                 Content
             vector unsigned char                             16 8-bit unsigned chars
             vector signed char                               16 8-bit signed chars
             vector unsigned short                            8 16-bit unsigned halfwords
             vector signed short                              8 16-bit signed halfwords
             vector unsigned int                              4 32-bit unsigned words
             vector signed int                                4 32-bit signed words
             vector unsigned long long                        2 64-bit unsigned doublewords
