This is a new one to me... what os/hardware are you running on?  Ah,
maybe you're using a more recent gcc?

I get this problem too.  Doesn't happen on FreeBSD.  On Linux, you can
get one step farther by configuring with --enable-staticvm and(?) 
--enable-staticlib.  The static linking seems to resolve the gmonparam
problem (gmonparam is defined in libc).   This isn't unique to kaffe,
a 5-line C program that uses the extern _gmonparam from <sys/gmon.h>
has the same problems (Linux/x86, Debian Testing).

However, statically linking Kaffe just changes the problem: I then get
a bunch of undefined symbols in libgmp (things like "undefined
reference to `__mpn_get_str'".  Somehow libgmp isn't working with
static linkage (?).

Haven't investigated any further.  I won't get a chance to play with
this for a while, so feel free to fix it before then!  :)
