Re: Problems with recent expat/gdb changes

[Daniel Price <daniel dot price at gmail dot com>]

Thanks for the followups.  Rather than modify the code, my short-term
workaround was to add "--disable-expat --with-expat=no" to the "extra
gdb configure args" since the target in this particular case does not
need XML support.

Personally I think the answer is that, when building a static
cross-gdb, expat should just always be built.
