Souce compile errors
Old bug opened on google code showed that workaround for the pypi install failures should be to download latest source and compile as such:
python setup.py build --compiler=mingw32
python setup.py install

tseries.c has two errors stopping compilation

pandas\lib\src\tseries.c: In function '__Pyx_c_absf':
pandas\lib\src\tseries.c:18906:25: error: #if with no expression
pandas\lib\src\tseries.c: In function '__Pyx_c_abs':
pandas\lib\src\tseries.c:19026:25: error: #if with no expression
pandas\lib\src\tseries.c: At top level:

should that be #ifdef?
