USE_DL_EXPORT is to be defined only when building the Win32 (and Cygwin)
DLL core not when building extensions. When building Win32 Python,
USE_DL_IMPORT is implicitly defined in PC/config.h when USE_DL_EXPORT is
not. Explicitly defining USE_DL_IMPORT will cause the macro redefinition
warning indicated above -- but no other ill or good effect.
Another way to solve your problem without using the "/export:init_sre"
link option is by patching PC/config.h with the attached. When I was
converting Cygwin Python to use a DLL core instead of a static library
one, I wondered why the USE_DL_IMPORT case was missing the following:
#define DL_EXPORT(RTYPE) __declspec(dllexport) RTYPE
Anyway, sorry that I caused you some heartache.
Jason
P.S. If this patch is to be seriously considered, then the analogous
change should be done for the other Win32 compilers (e.g. Borland).
