gcj patches for cygwin gcc-3.1

[Billinghurst, David (CRTS)]

There is more work in store before it really works.  All I have done
is get rid of a few compile time errors and patch the testsuite. There 
are bugs in the libjava libraries. 

None of these patches are in the main 3.1 branch.  All but the 
configure.host patch, which is required to build with unmodified
binutils, are in the 3.2 branch.  

At present I bootstrap with a gcc/ada version of gcc-3.1 using the
following options.  Note that 
 - ARFLAGS=crP is required to build libjava
 - you can't make gnatlib_and_tools without an ada bootstrap compiler

You need dejagnu-1.4.2 to run the g++ tests.  Even with that, "make check" 
will die a horrible death in libjava without a very nasty hack to
/usr/share/dejagnu/remote.exp (below) to work around another problem - 
possibly a cygwin bug - that I haven't followed up.

David,


Thanks for your hard work!  I truly hope this will lead to the day when 
I can  finally drop that crappy JDK with its !@#$ing windows path 
conventions.  I think it is a bigger PITA then anything else.


Cheers,

Nicholas
