problem with microblaze gcc toolchain

Hi

I'm starting to use the gnu mb-gcc compiler but I get this error
message:

mb-gcc test1.c

/cygdrive/d/xilinx/gnu/microblaze/nt/bin/../lib/gcc/microblaze/
3.4.1/../../../../microblaze/bin/ld: can't open input file: /cygdrive/
d/xilinx/gnu/microblaze/nt/bin/../lib/gcc/microblaze/3.4.1/../../../../
microblaze/bin/ld
collect2: ld returned 1 exit status

I don't know why this problem appears. The file ld is in such
directory. May be some issues with cygwin?

Thanks
Manuel
