For Windows visual C compiler, that is true. I do not know about gcc on
*nix. I have gotten the impression that it is not necessarily so, except
as the C api has changed in a way that affects the extension library.
(Given that 3.3 is 3 months old, after 6 months of alpha/beta releases,
and has some major improvements, it is past time for libraries that need
recompiling to be so.)

Given that python3 and python3-dbg import the same PyQt4 file, and that
you spell PyQt4.QtCore the same (I checked), I am as surprised as you.
Perhaps there is a bug in the import of the dbg build finding modules in
packages, but that is so basic, that would surprise me also. Try running
test/test_imp, _import, _importhooks, _importlib with both binaries
(because you are looking for a different).

On Windows, with 3.3, interactively in IDLE, I get
>>> import test.test_imp as t; t.test_main()

....
Ran 29 tests in 0.134s
OK (skipped=1)
....
Ran 48 tests in 0.953s
OK (skipped=4)
....
Ran 4 tests in 0.169s
OK
....
Ran 288 tests in 1.684s
OK (skipped=2)

Note that the above invocation runs in verbose mode, so if there is a
difference, you can find the specific test. The skips are usually system
specific. For instance, the one skip in the first batch is

test_issue5604 (test.test_imp.ImportTests) ... skipped "can't run this
test with mbcs as filesystem encoding"

The others were for other posix-windows differences.

No. I stuck to what looked like might be easier.
