NO_SHARED_VMLIBRARY (was: Trampoline in m68k)

Still, I don't understand newly introduced libtool environment...

In old (say, 1.0.b3) release, 'config/i386/trampolines.c' has two
trampoline codes one for shared and the other one for static lib,
and two codes are ifdefed based on the compile time def (NO_SHARED_VMLIBRARY).
But in newer (say 1999/2/27 snap) release, the code is modified
not to use shared version.

I guess this change comes from the introduction of libtool but not
so sure. Anyone has clear idea of why it happens?

Going back to the m68k/netbsd1.3.1 issue, when I made modification to
'config/m68k/trampolines.c' as the patch attached, the test script
starts to work. At least, HelloWorldApp.class can be executed.
But when this test script fails for compiling, and the error is
	assertion "cc != 0" failed: file "../../../kaffe-snap/kaffe/kaffevm/support.c", line 169

This assertion fail means lookupClass fail at some point. But the
core file I get by this assertion fail is not accepted by gdb, and
I can get backtrace of it...
