db_185.h has renamed that function to __db185_open, which it does in DB 3.1. So don't check whether the function is in -ldb.

/* Interface for threads.
A module that plans to do a blocking system call (or something else
that lasts a long time and doesn't touch Python data) can allow other
threads to run as follows:
...preparations here...
Py_BEGIN_ALLOW_THREADS
...blocking system call here...
Py_END_ALLOW_THREADS
...interpret result here...
The Py_BEGIN_ALLOW_THREADS/Py_END_ALLOW_THREADS pair expands to a
{}-surrounded block.
To leave the block in the middle (e.g., with return), you must insert
a line containing Py_BLOCK_THREADS before the return, e.g.
if (...premature_exit...) {
Py_BLOCK_THREADS
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
An alternative is:
Py_BLOCK_THREADS
if (...premature_exit...) {
PyErr_SetFromErrno(PyExc_IOError);
return NULL;
}
Py_UNBLOCK_THREADS
For convenience, that the value of 'errno' is restored across
Py_END_ALLOW_THREADS and Py_BLOCK_THREADS.
WARNING: NEVER NEST CALLS TO Py_BEGIN_ALLOW_THREADS AND
Py_END_ALLOW_THREADS!!!
The function PyEval_InitThreads() should be called only from
initthread() in "threadmodule.c".
Note that not yet all candidates have been converted to use this
mechanism!
