  I don't recommend to include iGCC 2.4.0 into NetBSD as primary compiler;
  I got internal errors several times when building Xfree server.

( e.g. 
   cfbply1rctG.c: In function `cfbFillPoly1RectGeneral':
   cfbply1rctG.c:305: internal error--insn does not satisfy its constraints:
   (insn:HI 449 1143 450 (parallel[ 
               (set (reg:SI 0 %eax)
                   (div:SI (reg:SI 0 %eax)
                       (reg:SI 1 %edx)))
               (set (reg:SI 1 %edx)
                   (mod:SI (reg:SI 0 %eax)
                       (reg:SI 1 %edx)))
           ] ) 104 {divmodsi4} (insn_list 1143 (nil))
       (nil))
   gcc: Internal compiler error: program cc1 got fatal signal 6
                                                                    )

  On the other hand, it may be good for experiments (necessarily backed 
  with stock GCC 2.4.5 )
