[Bug libgcj/13212] JNI/CNI AttachCurrentThread does not register thread with garbage collector

["arno at heho dot snv dot jussieu dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

------- Comment #17 from arno at heho dot snv dot jussieu dot fr  2005-10-23 00:28 -------
I quickly wrote a testcase to illustrate my point (attached jnew.java Makefile
gc-thread-register.cc) :

Compiling and running gives : 

  ./gc-thread-register 
  Starting first thread ...done
  Collecting from unknown thread.
  Abort trap (core dumped)

  (I know I develop and test on freebsd for which boehm-gc-threading is not
Tier-1, but :)

Compiling and running with FAKE_GC_CONFIG (set correct include path in
Makefile) defined gives :

  ./gc-thread-register 
  Starting first thread ...done
  Starting second thread ...done

NB, this does not necessarily explain (for me) why JvAttachCurrentThread()
fails in some situations (as is the essence of this PR), I just thought that
clearing up the interactions between gcj, boehm-gc and thread-lib might help in
nearing down the causes. 

PS, I thought the attachments where just for this note
