no vtable thunks

["Glenn W. Bach" <glenn at dodgson dot wonderland dot caltech dot edu>]

I am trying to compile a series of c++ libraries and programs with egcs
1.1b. Since our code uses both multiple inheritance and virtual inheritance
it is affected by the thunks bug. I recompiled everything (libstdc++ and
all of our libraries and code) with the -fno-vtable-thunks and now I'm
getting some strange errors. It reports that all of the references to
virtual tables are undefined:

code/CBStylerTable.cc:77: undefined reference to `JXStringTable::JTable virtual table'
code/CBStylerTable.o: In function `CBStylerTable::~CBStylerTable(void)':
code/CBStylerTable.cc:150: undefined reference to `JXStringTable::JTable virtual table'
code/CBStylerTableInput.o: In function `JXKeyModifiers::meta(void) const':
./../include/jcore/JPoint.h(.text+0xd1): undefined reference to `JXStringTableInput::JTextEditor virtual table'
code/CBStylerTableInput.o: In function `CBStylerTableInput::~CBStylerTableInput(void)':
code/CBStylerTableInput.cc:48: undefined reference to `JXStringTableInput::JTextEditor virtual table'
code/CBKeyScriptTableBase.o: In function `JPoint::JPoint(void)':
./../include/jcore/JPoint.h(.text+0x101): undefined reference to `JXStringTable::JTable virtual table'
code/CBKeyScriptTableBase.o: In function `CBKeyScriptTableBase::~CBKeyScriptTableBase(void)':
code/CBKeyScriptTableBase.cc:67: undefined reference to `JXStringTable::JTable virtual table'

Any clues as to the cause of this would be appreciated.
