Unfortunately we cannot help you as this is the mailing list for binutils
issues, and the code above is part of GDB, not the binutils.  If you resend
your email to gdb@sourceware.org you will be more likely to get some help.

If/when you do resend your email, it would help to mention which version of
the gdb sources you are compiling.

Cheers
   Nick
