problem compiling Python bindings under cygwin

Hi everyone,

after successfully compiling and installing quantlib using cygwin (as far as I can tell anyway), I have moved on to trying to compile and install the python swig wrappers. Near the beginning of the build process (when calling "python setup.py build"), I get the following 4 messages:

gcc: /GR: No such file or directory
gcc: /FD: No such file or directory
gcc: /Zm250: No such file or directory
gcc: /MT: No such file or directory

which may or may not be important. It continues on after that. It chugs along for a while with lots of warnings along the lines of "warning: '__tmp' might be used uninitialized in this function" which I suspect aren't important, and then finally dies with the error: "error: command 'gcc' failed with exit status 1".

The final portion of output before it dies is:

QuantLib/quantlib_wrap.cpp:4779:   instantiated from `static int swig::traits_asptr_stdseq<Seq, T>::
asptr(PyObject*, Seq**) [with Seq = std::vector<std::string, std::allocator<std::string> >, T = std:

Any ideas? I am using python 2.5 and I have successfully compiled other unrelated C extensions for Python with my current setup. Thanks,
