I wonder why instead of fooling with linker flags (which may
easily fail if sombody needs different way of linking) you do
not take the obvoius approach of renaming offending symbol
using apropriate prefix.

BTW: The same (even more) applies to the library in question:
in C public symbol "create_stack" (without a prefix) is a disaster
waiting to happen.
