111 void coff_solib_create_inferior_hook()
115 When gdb starts up the inferior, the kernel maps in the shared
116 libraries. We get here with the target stopped at it's first
117 instruction, and the libraries already mapped. At this point, this
118 function gets called via expansion of the macro
119 SOLIB_CREATE_INFERIOR_HOOK.
