ASCEND code in base/generic only EXPORTS symbols, no imports.

FREESTEAM_BUILDING_LIBASCEND (building libascend.so aka ascend.dll)
or FREESTEAM_BUILDING_INTERFACE (building for example _ascpy.dll or
ascendtcl.dll), act respectively to declare symbols as being
*exported* or *imported*.
New versions of GCC are able to make use of these declarations
as well.
