cygwin compatibility

[GoogleCodeExporter]

What steps will reproduce the problem?
1.import pypyodbc under cygwin

What is the expected output? What do you see instead?
OdbcNoLibrary exception raised since the sys.platform instpection around line 
#490 of pypyodbc.py doesn't include 'cygwin'.  However, the proper way to load 
the native odbc dll would then be something like:

ODBC_API = ctypes.cdll.LoadLibrary('/cygdrive/c/WINDOWS/system32/odbc32.dll')

So I'm not sure how that should best be implemented.

What version of the product are you using? On what operating system?
pypyodbc 0.8.7
cygwin 1.7.17-1 running on Windows XP 

Please provide any additional information below.
