Re: linking to Math library with OSKit 20000202

With the following link command:

kissmeimage: /home/jewel/oskit-install/lib/oskit/multiboot.o $(DEPENDLIBS) 
$(MYOBJECTS)
        $(LD) -Ttext 100000 $(LDFLAGS) $(OSKIT_LDFLAGS) \
        -o $@ $(filter-out %.a,$^) \
        -loskit_clientos -loskit_startup -loskit_com -loskit_freebsd_c
	-loskit_kern -loskit_fsnamespace -loskit_memfs -loskit_lmm /home/jewel/oskit-install/lib/oskit/crtn.o -loskit_posix
	-loskit_freebsd_dev  -loskit_freebsd_m

I get errors for missing pthread functions (as expected), but I also have
errors for:

When I link against -loskit_c as well as -loskit_freebsd_c these go away
and I am left with only the pthread references.

When add -loskit_threads, I get:

What is missing here?

No, I appreciate your help very much!

Am I using functions that are missing in the FBSD library but present in
the minimal library?
