[Eli Zaretskii]

branch: master
commit 5fcc777ff36c3102ddddd2fb932cb8d0b7cc2741
Author: Eli Zaretskii <address@hidden>
Commit: Eli Zaretskii <address@hidden>

    Fix last change with thread marking under GC_CHECK_MARKED_OBJECTS
    
    * src/thread.c (primary_thread_p): New function.
    * src/alloc.c (mark_object): Use 'primary_thread_p' to bypass tests
    meant for thread objects allocated dynamically.
    * src/thread.h (primary_thread_p): Add prototype.
