Hi,
this is my first email to this list, I'm currently porting python to some
platforms with limited capabilities and so I thought it would be a good idea
to subscribe here.
While doing the porting, I found two small problems in Python 2.5.1:
If Py_USING_UNICODE is disabled, in Python/ast.c decode_unicode() still calls
unicode-related functions, which leads to undefined references when linking.
If HAVE_DYNAMIC_LOADING is disabled, in Python/import.c
_PyImport_DynLoadFiletab is still initialized, which also leads to undefined
references when linking, since then no source file which defines this
variable is used.
A patch against 2.5.1 is attached.
Best regards
Alex
