Why Remove libstdc++-v3-dg.exp's Irix code?

[Jeffrey Oldham]

Your 07Aug libstdc++-v3 changes included removing this code from 3.1's
libstdc++-v3/testsuite/lib/libstdc++-v3-dg.exp:

- # On IRIX 6, we have to set variables akin to LD_LIBRARY_PATH, but
- # called LD_LIBRARYN32_PATH (for the N32 ABI) and LD_LIBRARY64_PATH
- # (for the 64-bit ABI).  The right way to do this would be to modify
- # unix.exp -- but that's not an option since it's part of DejaGNU
- # proper, so we do it here, by trickery.  We really only need to do 
- # this on IRIX, but it shouldn't hurt to do it anywhere else.
- proc libstdc++-v3_set_ld_library_path { name element op } {
-   setenv LD_LIBRARYN32_PATH [getenv LD_LIBRARY_PATH]
-   setenv LD_LIBRARY64_PATH [getenv LD_LIBRARY_PATH]
- }
- 
- trace variable env(LD_LIBRARY_PATH) w libstdc++-v3_set_ld_library_path

Without it, all libstdc++-v3 execution tests fail for mips-sgi-irix6.5
gcc 3.1.  May we have it returned to the mainline branch?

I have attached:
1) the patch
2) a summary of the libstdc++-v3 regression tests results without
   using the patch (along with other results)

Thanks,
Jeffrey D. Oldham
