Pbm with Kaffe 0.8.2 on Solaris

[Daniel.Veillard at imag.fr]

When compiling 0.8.2 with gcc 2.7.2 on solaris 5.5 (Ultra) :

First I had to patch some Makefile.in to have Kaffe-0.8.2 compile
when using static libs (patch at the end of the mail). I guess this is
not specific to Solaris. BTW the patch break the dynamic linking, for
sure :-\
If Kaffe is compiled with -g the context-switching seems to be broken.

~/opera/classes/amaya -> gdb kaffe
(gdb) r sun.tools.javac.Main HTTPAccess.java

      muxWaiters = 0x0, __align__ = 0}, cv = {cvWaiters = 0x0, mux = 0x0}}, 
  name = 0x99d88, priority = 5, next = 0x0, PrivateInfo = 1, eetop = 0, 
  single_step = 0, daemon = 0, stillborn = 0, target = 0x0, 
  interruptRequested = 0, group = 0xa4548}

      muxWaiters = 0x0, __align__ = 0}, cv = {cvWaiters = 0x0, mux = 0x0}}, 
  name = 0xa6e78, priority = 10, next = 0x0, PrivateInfo = 2, eetop = 0, 
  single_step = 0, daemon = 1, stillborn = 0, target = 0x0, 
  interruptRequested = 0, group = 0x0}
(gdb)

This problem also show off with 0.8.0 ...
The same javac compilation went fine with a binary generated with "-g -O"
CFLAGS.
Now trying to run Amaya with Kaffe embedded I got

  However, going back to Kaffe 0.8.0 solved the problem.

  Keep up the good work, it seems that so many people are investing time
in kaffe it can only be a success ! That remember me when I started using
Linux five years ago (0.12b), I wish the same success story for Kaffe,
