[ECOS] C++ Linker error

[Tim michals <tcmichals at yahoo dot com>]

Background:  using arm-elf-gcc 3.2.1 on XP. I'm
compiling fltk with the following flags:

-g -O2 -Wall -Wunused  -ffunction-sections
-fdata-sections -fno-rtti -fno-exceptions
-finit-priority

(I did not include -fvtable-gc, if I use this flags
the linker gets a protection fault, still trying to
figure this out )

I'm trying to link FLTK (which is a graphics library)
and I'm getting the following errors:

.44/libnx11.a -Xlinker -Map -Xlinker ecos_app.map

Any clues? what does the flag -fvtable-gc do?
