-/* When handling shared libraries, GDB has to find out the pathnames
-   of all shared libraries that are currently loaded (to read in their
-   symbols) and where the shared libraries are loaded in memory
-   (to relocate them properly from their prelinked addresses to the
-   current load address).
-
-   Under OSF/1 there are two possibilities to get at this information:
-   1) Peek around in the runtime loader structures.
-      These are not documented, and they are not defined in the system
-      header files. The definitions below were obtained by experimentation,
-      but they seem stable enough.
-   2) Use the undocumented libxproc.a library, which contains the
-      equivalent ldr_* routines.
-      This approach is somewhat cleaner, but it requires that the GDB
-      executable is dynamically linked. In addition it requires a
-      NAT_CLIBS= -lxproc -Wl,-expect_unresolved,ldr_process_context
-      linker specification for GDB and all applications that are using
-      libgdb.
-   We will use the peeking approach until it becomes unwieldy.  */

-
-	In most (all?) cases the shared object file name recorded in the
-	dynamic linkage tables will be a fully qualified pathname.  For
-	cases where it isn't, do we really mimic the systems search
-	mechanism correctly in the below code (particularly the tilde

-SYNOPSIS

-  
-DESCRIPTION
-
-	When gdb starts up the inferior, it nurses it along (through the
-	shell) until it is ready to execute it's first instruction.  At this
-	point, this function gets called via expansion of the macro
-	SOLIB_CREATE_INFERIOR_HOOK.
-	For a statically bound executable, this first instruction is the
-	one at "_start", or a similar text label. No further processing is
-	needed in that case.
-	For a dynamically bound executable, this first instruction is somewhere
-	in the rld, and the actual user executable is not yet mapped in.
-	We continue the inferior again, rld then maps in the actual user
-	executable and any needed shared libraries and then sends
-	itself a SIGTRAP.
-	At that point we discover the names of all shared libraries and
-	read their symbols in.
-
-FIXME
-
-	This code does not properly handle hitting breakpoints which the
-	user might have set in the rld itself.  Proper handling would have
-	to check if the SIGTRAP happened due to a kill call.
-
-	Also, what if child has exit()ed?  Must exit loop somehow.
