macscp.exp failures

[Andreas Schwab]

I see many failures for the macscp tests:

The contents of the .debug_macinfo section look reasonable.  Is this a
known bug?

Joseph noticed these also; so far, I've only worked out that they
passed with GCC 4.2 and failed with GCC 4.3.

Comparing those:

- DW_MACINFO_start_file - lineno: 1 filenum: 2
+ DW_MACINFO_define - lineno : 0 macro : __DECIMAL_BID_FORMAT__ 1
+ DW_MACINFO_start_file - lineno: 63 filenum: 2
  DW_MACINFO_define - lineno : 27 macro : _STDIO_H 1
- DW_MACINFO_start_file - lineno: 28 filenum: 3
+ DW_MACINFO_start_file - lineno: 3647 filenum: 3
  DW_MACINFO_define - lineno : 20 macro : _FEATURES_H 1

Tom, could this be mapped-location breakage?  Those line numbers look
implausible.

It is possible.  I will look at it.

I found the problem.  I will regtest the gcc patch, then submit it
later today, or tomorrow.
