 Ooops. One shouldn't change test cases in the very last minute :-(
 
 __attribute__ ((mode (TI))) int f (void) { }
 
 (note TI instead of SI) indead crashes on 3.2/3.3 as described and
 issues an error with 2.95.3 on sparc:
 
 7227-2.c:2: no data type for mode `TI'
 
 However, this testcase results in an error with all gcc Versions on i386.
 
     regards  Christian
