gcc-2.3.1: g++ doesn't handle -l well
#1375
Author: Joe Korty

The script g++ fails to correctly link the below c++ program, since the place
it puts the -lg++ in the underlying call to gcc is *after* any user-specified
-l options, not before.  This causes link edit failures, since some routines
in -lg++ call routines in -lmath, and there is no way using g++ that -lmath
can be specified after the embedded -lg++.



	g++ complex.C -lmath			link failures
	gcc complex.C -lmath -lg++		what the above invokes
	gcc complex.C -lg++ -lmath		works

A possible ad-hoc is for g++ to append `-lg++ -lmath' to the command
line, not just `-lg++'.

This was run on an m88k system V release 3 style OS.
