-  /* This function is expected to handle ELF shared libraries.  It is
-     also used on Solaris, which can run either ELF or a.out binaries
-     (for compatibility with SunOS 4), both of which can use shared
-     libraries.  So we don't know whether we have an ELF executable or
-     an a.out executable until the user chooses an executable file.
-
-     ELF shared libraries don't get mapped into the address space
-     until after the program starts, so we'd better not try to insert
-     breakpoints in them immediately.  We have to wait until the
-     dynamic linker has loaded them; we'll hit a bp_shlib_event
-     breakpoint (look for calls to create_solib_event_breakpoint) when
-     it's ready.
-
-     SunOS shared libraries seem to be different --- they're present
-     as soon as the process begins execution, so there's no need to
-     put off inserting breakpoints.  There's also nowhere to put a
-     bp_shlib_event breakpoint, so if we put it off, we'll never get
-     around to it.
-
-     So: disable breakpoints only if we're using ELF shared libs.  */
