[Mono-dev] Undefined static pointer link error

[GrahamNewton]

Hi
I am trying to cross compile the latest trunk SVN checkout of mono.  In
mono/utils/mono-value-hash.c line 69 there is this line of code:
static gpointer KEYMARKER_REMOVED = &KEYMARKER_REMOVED;
which never appears to be referenced anywhere else.
Apart from the fact that I have no idea what this is for or does, I get an
undefined symbol linker error.
Examining mono-value-hash.o shows this:

 586-nm mono-value-hash.o
         U KEYMARKER_REMOVED

hacking the Makefile by hand to remove -O2 compiler switches
I get 
586-nm mono-value-hash.o
00000000 d KEYMARKER_REMOVED

My gcc version is
586-gcc --version
586-gcc (GCC) 4.2.0 20070126 (prerelease) (MontaVista 4.2.0-3.0.0.0702771
2007-03-11)

Can someone explain what KEYMARKER_REMOVED does and do similar problems
occur when compiling for other platforms?
Thanks
Graham
