Hi Richard,

This looks like the CONST problem with tcl migrating between 8.3 and 
8.4... try defining USE_NON_CONST and see if it makes a difference 
(-DUSE_NON_CONST). I don't know why it would crop again on a 64bit build.

ps A google search reveals that the above has helped someone build a tcl 
extension on AMD64
