      Hmm.  There's some disagreement on this issue:

      1999-04-06  Stan Shebs  <shebs@andros.cygnus.com>

	      * solib.c (clear_solib): Don't call disable_breakpoints_in_shlibs,
	      this breaks rerunning on sun4 native.

   Oops!  I missed that one.  What does Stan mean by sun4 native?  Is
   that a running SunOS 4, or SunOS 5 (Solaris 2)?

SunOS 4.  (A Cygnus-ism I suppose - "sun4" means 4.x, "sol2" means 5.x.)

   Not callinf
   disable_breakpoints_in_shlibs breaks rerunning on both Linux and the
   Hurd, and I suspect that it breaks on other systems with ELF shared
   libraries as well.

Sigh.  We really need a test case for this, so that test runs catch.

   If calling disable_breakpoints_in_shlibs only breaks SunOS 4, which I
   suspect since there is also a bug report concerning Solaris, the code
   could be wrapped in #ifdef SVR4_SHARED_LIBS.

That seems rational, although I want to understand the issue this
time instead of fixing symptoms.  Then we can write a comment on this
and not have to be puzzled ever again (on this subject anyway :-) ).
