[RELEASED] Kaffe 0.8.2

[Daniel Veillard]

>KAFFE v0.8.2 - A JIT and interpreting virtual machine to run Java(tm)* code

 I'm probably doomed but I can't get 0.8.1 nor 0.8.2 to work.
I'm running on Linux 2.0.28, RedHat 4.0.
With 0.8.2 I tried first to compile it without shared library,
the configure script then produces an incorrect output :

make[5]: Entering directory `/users/veillard/opera/LINUX-ELF/kaffe-0.8.2/packag
es/biss-net.com/APIawt/lib'
Makefile:36: *** commands commence before first target.  Stop.
make[5]: Leaving directory `/users/veillard/opera/LINUX-ELF/kaffe-0.8.2/package
s/biss-net.com/APIawt/lib'

Then at the end of make in kaffe-0.8.2/kaffe/kaffevm
ranlib libkaffe_vm.a.0.82 -lm -ldl
ranlib: -lm: No such file or directory
make[3]: *** [libkaffe_vm.a.0.82] Error 9

Seems that the LINKXLIB macro of configure is wrong in the case of
configure --enable-staticlib 
at least on the Linux platform. I didn't even find out in configure
where this macro is set up ... Well I didn't succeed in compiling
without shared libs.

So I tried to reenable the dynamic linking, it compiles and install fine.
I set up LD_LIBRARY_PATH to the the directory of kaffe shared libs,
alas kaffe doesn't seems to work anymore. I tried to compile one of my
java classes, it segfault :

        libm.so.5 => /lib/libm.so.5.0.6
        libdl.so.1 => /lib/libdl.so.1.7.14

I dont understand as CALL_KAFFE_FUNCTION_VARARGS macro didn't change between
0.8.0 and 0.8.2 and the code in support.c didn't change much either. 

  I feel confused, what's happening ? The only difference I noticed is the
change from object to Object ...

Daniel, stuck with 0.8.0
