picewise linking and MS lib.exe

[Christopher Hulbert]

Piecewise linking with the MS archiver (lib) doesn't work. Every
invocation of the lib clobbers the old one. The solution is to list
the library as the first "object" (really anywhere should be fine) in
the next lib command. I'm not sure how to patch this. It looks like
the piecewise linking code in ltmain.m4sh doesn't depend on what
linker it's using. Any ideas on how best to patch this?

e.g.

address@hidden ~
$ cat test1.c test2.c
#include <stdlib.h>

double add(double x,double y)
{
   return (x+y);
}
#include <stdlib.h>

double sub(double x,double y)
{
   return (x-y);
}

address@hidden ~
$ pgcc -c test1.c test2.c
test1.c:
test2.c:
