Seems that we have one problem with gcc-3.1.X and DWARF2 debugging info.

I tried to change to DWARF2 as default debugging info and run into trouble.
GDB-5.2 (and also rather recent development snapshot of GDB) does not recognize
debugging info of executables generated by this build (currently only tested
executables from build of stage2 of gcc bootstrapping):

D:\...cc-3.11-prerelease\build.djg\gcc>gdb cc1.exe

This GDB was configured as "i386-pc-msdosdjgpp"...Dwarf Error: wrong version in
compilation unit header.

Tried to drop support of COFF debugging info, but it didn't help. Currently I 
don't know what caused this problem. 

I have already met something similar when tried to use libgdb.a and libstdcxx.a 
rebuilt with DWARF2 debugging info as far as I remember
