 Building gdb+dejagnu-20040103 on sparc-sun-solaris2.8 with gcc 3.1 -m64
 gave a gdb
 that can set breakpoints in 32-bit binaries, in itself and another 64-bit
 binary built with gcc-3.1.
 
 => The problem is FIXED!
 
 This 64-bit binary built with a prerelease gcc 3.0.3 gives an I/O error
 setting the breakpoint

 (Probably the correct response to being unable to debug 64-bit binaries
 built with obsolete prerelease compilers and binutils
 versions is: Don't do that then).
