Conflicting type ULONG on Cygwin x64

[nowox]

While compiling PyODBC on Cygwin 2.1 x64 I get this issue:

In file included from /usr/include/sql.h:89:0,
                 from src/pyodbc.h:53,
                 from src/buffer.cpp:12:
/usr/include/sqltypes.h:220:24: error: conflicting declaration ‘typedef long unsigned int ULONG’

 typedef DWORD ULONG;
               ^
error: command 'gcc' failed with exit status 1

According to Cygwin mailing list (here, a possible solution (that eventually allow me to build pyodbc) is this one:

#ifdef __LP64__
  typedef unsigned int ULONG;
#else
  typedef unsigned long ULONG;
#endif
