incorrect? link order for mingw gcj

incorrect? link order for mingw gcj

[aking]

There seems to be a library link order problem with the current cvs 3.1 
branch of the mingw32 cross compiler.  A simple hello world compiles 
and runs fine, however, this simple java program fails to compile:

public class GCJTest
{
  public static void main( String[] args )
  {
    try
    {
      Thread.sleep( 2000 );
    }
    catch( Exception e ) {}
  }
}

the error is:
aking@nanostorm:~/gcj-test$ i686-pc-mingw32-gcj --main=GCJTest -o /tmp/gcjtest.exe GCJTest.java
/home/aking/mingw-gcc/lib/gcc-lib/i686-pc-mingw32/3.1/../../../../i686-pc-mingw32/lib/libgcj.a(exception.o): In function `abort':
/home/aking/compile/mingw-gcj/bin/i686-pc-mingw32/libjava/../../../gcc/libjava/exception.cc:27: multiple definition of `abort'
/home/aking/mingw-gcc/lib/gcc-lib/i686-pc-mingw32/3.1/../../../../i686-pc-mingw32/lib/libmsvcrt.a(ds00510.o)(.text+0x0): first defined here

However, if I add in the libraries '-lgcj -lmsvcrt', it compiles and runs fine:

aking@nanostorm:~/gcj-test$ i686-pc-mingw32-gcj -lgcj -lmsvcrt --main=GCJTest -o /tmp/gcjtest.exe GCJTest.java
aking@nanostorm:~/gcj-test$ 

I know almost nothing about how the configure/make build system 
works, so I have no idea where to look, sorry.  Anyways, I'll continue
on with some other patches I'm working on for mingw32 version.

The file libgcj.spec (which is generated from libgcj.spec.in) specifies 
what arguments gcj passes to the linker. You can probibly at least work 
around the problem in there.

I think I fixed this -- could you cvs update and try again?

Could you please add this to the branch as well? It fixed my compilation 
error of libjava on darwin.

Thanks,

Andreas

I thought I applied it to both branch and trunk -- do you see differently?

Thanks.
