_imp__* linking errors when compiling extension using Mingw

[Joonas Paalasmaa]

Hi,

When compiling Sketch's streamfilter C extension the errors below are
raised during linking. What could cause the errors?
(Python 2.3, MinGw 1.1 with GCC 2.95.3-6, Windows 98)

Here are the occurrences of FilterType that may be relevant:
-------
C:\sketch\sketc h-0.7.12\Filter\f ilterobj.c: 949: PyTypeObject
FilterType = {
C:\sketch\sketc h-0.7.12\Filter\f ilterobj.h: 89: extern
DL_IMPORT(PyTyp eObject) FilterType;
-------

setup.py contents:
-------
from distutils.core import setup, Extension
filter_dir = "Filter/"
setup(name = "sketch", ext_modules=[
Extension("stre amfilter", [filter_dir+file name for filename in
("streamfilter. c", "filterobj. c", "linefilter .c",
"subfilefilter. c", "base64filter.c ","nullfilter.c ",
"stringfilter.c ", "binfile.c" , "hexfilter. c")])])
