   Understandable.  What the time frame for the 4.18 release?  Any
   idea of the rough plan for a follow up release?

4.18 should be finished this month, unless some kind of huge
showstopper materializes.  I'd like the next release to happen in less
than a year, with all the current goings-on, once/year is a little too
slow of a pace.

     1) Backtracing through sigtramps on Solaris is somewhat busted without
	my changes (the Solaris library contains functions which don't use
	%ebp as the frame pointer).  For example ... the backtrace from
	gdb.base/a1-selftest.exp (without my patch) shows:

Hmmm, that makes it a bug fix, not a new feature, therefore more
important to add! 1/2 :-)

     2) The egcs patch to eliminate the frame pointer by default on the
	x86 can't be installed until there's debugger support.

That's a pretty compelling point too.  I'm kind of tempted to go for
this change...
