Mainline build failure

[Kenneth Zadeck]

Steven, actually the last piece of mail I sent you was a lie. 
The bug I fixed is different.

The problem is that between the time that I check my code in an now, 
someone changed the representation of BASIC_BLOCK.

lorien:~/gccDFTest/gcc(27) diff basic-block.h  ../../gccBaseline/gcc
370c370
<   varray_type x_basic_block_info;
---
 >   VEC(basic_block,gc) *x_basic_block_info;
402c402
<   (VARRAY_BB (basic_block_info_for_function(FN), (N)))
---
 >   (VEC_index (basic_block, basic_block_info_for_function(FN), (N)))
414c414,415
< #define BASIC_BLOCK(N)                (VARRAY_BB (basic_block_info, (N)))
---
 > #define BASIC_BLOCK(N)                (VEC_index (basic_block, 
basic_block_info, (N)))
 > #define SET_BASIC_BLOCK(N,BB) (VEC_replace (basic_block, 
basic_block_info, (N), (BB)))

I will change my code and submit something when I get it thru stage 1 build.
