I'm trying to compile distributed octave under cygwin and I'm having 
some trouble. Has anybody succeeded in doing this? I'm using distributed 
octave sp20040402. I can patch and compile octave and serially execute 
parallel code. When I try and compile the mpi pil everything is good 
until it tries to build the pil from the objects. Here's the mpiCC 
command it is attempting.

mpiCC -g -O2  -DUSE_MPI_API -DUSE_PARALLEL_CMD \
-I/usr/local/include/octave-2.1.45 \
-I/usr/local/include/octave-2.1.45/octave \
-I/usr/local/include -fPIC -DHAVE_CONFIG_H  -shared -o octave_mpi.pil \
pil_octave_mpi.o pil_mpi_comm.o pil_mpi_misc.o pil_mpi_tags.o \
pil_mpi_xrecv.o pil_mpi_xsend.o

I get pages of errors along the lines of:
pil_octave_mpi.o(.text+0x68): In function `pil_initialize':
.../mpi_pil-sp20040402/pil_octave_mpi.cc:69: undefined reference to 
`___gxx_personality_sj0'
pil_octave_mpi.o(.text+0xbd):.../mpi_pil-sp20040402/pil_octave_mpi.cc:71: 
undefined reference to `operator new(unsigned)'

I tried adding (in various combinations and with the appropriate -L's) 
-loctave -lcruft -lc -lstdc++ -lm   to no avail. I believe I've had 
similar problems before (something with the way cygwin handles refs to 
shared libs within shared libs I believe) but can't remember how I fixed 
it. Any thoughts?
