Seeing that GDB-5.2 was released I thought I'd give it a try.....

Tweaking pkgsrc to build it was trivial -- patch below....

It seems to work fine on i386, at least for 1.5W (i.e. prior to the
core-file format changes).

However it doesn't work at all on sparc, not for 1.5W, nor for 1.5ZC.
This is odd because 5.1.1 works well enough on 1.5W, and that it doesn't
seem to understand the new core file format is also strange since in my
peeks through the GDB master CVS repository it seemed as though all
Jason's changes for the new core format were included in the new
release, but I may be mistaken about that....  (maybe only for i386 and
arm?)

Anyways, here's the patch to the pkgsrc module in case anyone wants to
test further.  I won't send-pr unless this can be fixed and tested to
work on -current on more platforms....
