branch: feature/igc3
commit 89619f3762646662c8c8da9d3cc645c9ff3787a8
Author: Helmut Eller <[email protected]>
Commit: Helmut Eller <[email protected]>

    Don't define Weak_Key_Strong_Value if USE_EPHEMERON_POOL
    
    * src/lisp.h (enum hash_table_weakness_t): Define Weak_Key_Strong_Value
    only if !defined USE_EPHEMERON_POOL.
    * src/fns.c (hash_table_weakness_symbol): Add ifdefs for
    Weak_Key_Strong_Value.
    * src/igc.c (Vigc__dependency_replacements): Define it only
    if  if !defined USE_EPHEMERON_POOL.
