Upgrading to gcc 3.3.2, while a pain, fixed this.

I found a strange problem when compiling 0.5.3, however. The output is pasted
at the end of this email. It seems to be related to static vs shared linking.
When I alter the Makefile to remove the -static flag, the object files have
undefined references to __longjmp and such. I solved it by doing changing the
Makefile to do this:

/opt/gcc33/bin/gcc3  -static -Wl,-T,/home/jbrown105/qemu-0.5.3/i386-vl.ld  -o
qemu-fast vl.o osdep.o block.o monitor.o ide.o ne2000.o pckbd.o vga.o sb16.o
dma.o oss.o fdc.o mc146818rtc.o serial.o i8259.o i8254.o pc.o gdbstub.o sdl.o
libqemu.a -lm -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lm -L/usr/lib
-ldl -lutil -shared -lartsc -DPIC -fPIC -lpthread -L/usr/lib -lesd -laudiofile
-lm -L/usr/X11R6/lib -lX11 -lXext -lXxf86vm -lXxf86dga -lXv

So the libraries which cause trouble are linked shared but the object files
themselves and glibc itself are linked staticly. This seems to work, although
I haven't tried any real testing yet (just "qemu-fast --help"). I searched the
archives for information on this but I didn't find any, so I'm sending the info
here. (And yes I realize that I have this error because my system is broken.)
