A separate patch will be posted real-soon-now...

Here is what I committed:

2003-06-03  J. Brobecker  <brobecker@gnat.com>

        * alpha-osf1-tdep.c (alpha_osf1_skip_sigtramp_frame): Delete.
        (alpha_osf1_init_abi): Do not set skip_sigtramp_frame in tdep
        structure, field no longer exists.

There is still the alphanbsd-tdep.c file. I will take care of this one
momentarily.

Thanks for the hand,
