- This function is responsible for discovering those names and
- addresses, and saving sufficient information about them to allow
- their symbols to be read at a later time.

-SYNOPSIS
-
- void coff_solib_create_inferior_hook()

-DESCRIPTION
-
- When gdb starts up the inferior, the kernel maps in the shared
- libraries. We get here with the target stopped at it's first
- instruction, and the libraries already mapped. At this point, this
- function gets called via expansion of the macro
- SOLIB_CREATE_INFERIOR_HOOK.
