[plt-scheme] New language plugin: sPico

Can you show us your full command line?  The MinGW says its gcc
release should work like the official gcc releases.

My MzScheme extension Makefiles start with:

CFLAGS=++ccf -g ++ccf -fPIC --cc
LIBS=++ldf -lpthread ++ldf -lutil

        $(CC) -d `dirname $@` $(CFLAGS) $<

To compile all the objects, and then to link them as a dynamic library:

ALLOBJS= some-obj.o another-obj.o

my-extension.so: $(ALLOBJS)
        $(MZC) -v --linker $(GCC) --ld my-extension.so ++ldf -g ++ldf
-fPIC  $(LIBS) --ldf-show --ldl-show $(ALLOBJS)

In Windows I guess ".o" is replaced by ".obj" and if you keep getting
those errors, try adding "++ccf -lgcc" to the beginning of the CFLAGS
for mzc.
