Subject: 	* gdbserver/Makefile.in (gdbserver):  Use -lbsd. 	*
 gdbserver/remote-inflow{-sparc}.c (create_inferior):  Don't use a 	shell
 when running the child, as args have been expanded by the 	time we get
 here.  Simplify calling convention. 	* gdbserver/remote-server.c (main): 
 Use new calling convention 	for create_inferior, remove defunct code for
 coalescing argv. 	Remove extra calls to mywait(), as we no longer have
 to wade 	through a shell.
